> Quick answer: Buyers sourcing Urolithin A CAS 1143-70-0 should verify the chemical identity, assay target, batch COA, specification sheet, sample label, manufacturing route, packaging, MOQ, lead time and destination-market documentation before approving a supplier. The CAS number helps identify the material, but it does not by itself confirm assay, purity, origin, or suitability for a finished-product formula.
Urolithin A is a specialty ingredient that requires a specification-led sourcing process. Procurement teams, formulators and QA reviewers should compare the same set of technical and commercial fields across each supplier quotation. A clear CAS reference is useful for the RFQ, but the final purchase decision should be based on matched identity, analytical data, sample performance and batch documentation.
This guide is for supplement brands, functional food developers, contract manufacturers, importers and ingredient distributors evaluating Urolithin A CAS 1143-70-0 for B2B formulation projects.
What CAS 1143-70-0 tells a buyer
The CAS number is an identity reference used in technical files, supplier communication and import documentation. It is not a complete product specification.
| Buyer check | What to confirm | Why it matters |
|---|---|---|
| Chemical identity | Product name, CAS 1143-70-0 and material description | Prevents a quotation from combining different materials under a similar name |
| Assay target | Agreed purity or assay range and analytical method | Defines the grade being compared |
| Form | Powder appearance, particle or mesh direction and storage condition | Supports sampling, packaging and formulation review |
| Batch reference | Lot number on the COA, sample label and quotation | Creates traceability across approval steps |
| Source and route | Manufacturing route and source information available for buyer review | Helps QA teams assess documentation needs |
| Commercial terms | MOQ, packaging, lead time and sample availability | Determines whether the supply plan is workable |
Ask the supplier to place the CAS number, product name and grade on the same specification and quotation record. If the CAS number appears only in a sales message but not in the technical package, ask for a corrected document set before sample approval.
Urolithin A supplier specification checklist
Use this checklist to compare a Urolithin A supplier consistently.
### Identity and assay
Request the current specification sheet and representative COA. The documents should show the product identity, assay or purity target, test method, lot number, manufacturing date and applicable release limits. A number without a method is not enough for a quality comparison.
### Analytical method
Ask which method is used for identity and assay, how the result is reported, and whether the method is validated or internally qualified for the material. For a high-value specialty ingredient, the buyer should be able to match the method on the specification with the method shown on the batch COA.
### Physical properties
Record appearance, color, particle-size direction, bulk-density information if relevant, moisture or loss-on-drying limits, and storage conditions. These details affect blending, encapsulation, tablet development, powder handling and warehouse planning.
### Contaminant and quality files
Depending on the destination market and finished-product format, request the documents required for internal review, such as:
- Batch COA
- Specification sheet
- SDS or MSDS where required
- Microbiology information where applicable
- Heavy-metals or elemental-impurity information where applicable
- Residual-solvent statement where relevant to the manufacturing route
- Allergen and carrier declaration where applicable
- Country-of-origin and traceability information
- Packaging and storage statement
Do not assume every supplier uses the same document scope. Put the required files into the RFQ so that each quotation can be compared on the same basis.
Sample approval workflow for CAS 1143-70-0
A sample should be linked to the same grade and documentation that will support the commercial order.
- Send the sourcing brief. Include the CAS reference, target assay, finished-product format, estimated volume, destination market and required files.
- Request a matched sample. Ask for the sample lot, product label, specification sheet and representative COA.
- Review identity and assay documents. Confirm that the CAS number, material name, lot and test method are consistent.
- Run the buyer-side application test. Record powder handling, blend behavior, appearance, dispersion or other project-specific criteria.
- Review the commercial package. Compare MOQ, packaging, lead time, shipment documents and batch-release timing.
- Document approval. Record the approved grade, open questions, reference sample and conditions for a first purchase order.
This workflow gives procurement, R&D and QA teams one approval record instead of separate, unconnected email decisions.
Compare supplier documents before quotation
| Document | Main purpose | Questions for the supplier |
|---|---|---|
| Specification sheet | Defines the agreed material and limits | Does it show the CAS reference, grade, assay, method and storage? |
| Representative COA | Shows batch-level results from a lot | Does the lot number match the sample or commercial batch? |
| SDS or MSDS | Supports handling, storage and transport review | Is the document current and issued for the same material identity? |
| Process or source statement | Supports supplier and QA review | Is the manufacturing route described at a useful level? |
| Packaging specification | Defines the shipment format | Are inner liner, outer pack, net weight, label and pallet fields clear? |
| Export documents | Supports the shipment and destination review | Which files are available before dispatch and with the final lot? |
The supplier’s document package should be reviewed as a set. A strong COA cannot replace a missing specification sheet, and an SDS cannot replace batch analysis.
MOQ, packaging and lead-time questions
Specialty ingredient sourcing often fails when commercial details are left until after technical approval. Include the following questions in the first RFQ.
| Commercial field | Buyer question | Record |
|---|---|---|
| MOQ | What is the MOQ for the selected assay and packaging? | MOQ by grade and pack size |
| Sample | Is the sample from a commercial lot? | Sample quantity, lot and cost policy |
| Lead time | What is the standard production and dispatch lead time? | Production days and shipping handoff |
| Packaging | Which pack sizes and barrier materials are available? | Bag, drum, carton, liner and pallet |
| Label | Which identity, lot and storage fields appear on the label? | Label review status |
| Batch release | When is the final COA issued? | Pre-shipment or post-production |
| Repeat supply | Can the supplier retain a reference sample or support repeat lots? | Continuity plan |
Avoid turning an indicative term into a public guarantee. Confirm MOQ and lead time for the selected grade, quantity, packaging and destination in the quotation.
Supplier scorecard for Urolithin A sourcing
| Evaluation area | What to score | Example weight |
|---|---|---|

| Documentation | COA, specification, SDS/MSDS and traceability files are usable | 20% |
| Sample fit | Sample matches the approved grade and project requirements | 20% |
| Batch continuity | Supplier can explain lot control and repeat-order process | 15% |
| Commercial fit | MOQ, packaging and lead time fit the project plan | 10% |
| Communication | RFQ and technical questions receive clear answers | 10% |
Adjust the weights to match the buyer’s internal risk and approval process. Keep the scoring notes beside the supplier name so the decision can be audited later.
What to include in a Urolithin A CAS 1143-70-0 RFQ
Include the following fields in the initial request:
- Product name and CAS 1143-70-0 reference
- Target assay or purity range and analytical method
- Finished-product format and application category
- Sample quantity and evaluation timeline
- Estimated trial, first-order and annual volume

FAQ for Urolithin A buyers
It provides an identity reference for the material named in the technical and commercial documents. Buyers still need to confirm assay, analytical method, batch COA, source information, packaging and destination-market documentation.
Request a specification sheet, representative or batch COA, current SDS or MSDS where required, sample information, packaging details, traceability information and export files relevant to the shipment.
The sample and commercial lot may be different batches, but the product identity, grade and test method should be consistent. The final commercial lot should have its own batch COA before release.
Compare the same assay target, method, document package, sample basis, MOQ, packaging, lead time and shipment assumptions. A lower unit quote may not represent the same specification or service scope.
