Curcumin (Turmeric Extract) sourcing overview
For a Curcumin (Turmeric Extract) sourcing request, start with the exact catalog name and CAS 458-37-7, then define the commercial grade and measurable acceptance criteria. A shared name or identifier alone does not establish equivalence between supplier offers.
Procurement context: The written name indicates a source-derived material. Source identity, processing route, marker or activity basis and any carrier system must be defined before offers can be treated as equivalent.
Product identity and catalog reference
| Product name | Curcumin (Turmeric Extract) |
|---|---|
| CAS No. | 458-37-7 |
| Procurement family | Source-derived ingredient |
| Verification status | Confirm every catalog value against the current offered specification, SDS and batch documentation. |
Identity details to preserve
- Exact catalog name: Use “Curcumin (Turmeric Extract)” as the initial requested name and resolve any supplier synonym to the same documented identity.
- CAS screening reference: The catalog associates 458-37-7 with this listing. Verify the number on the offered specification, SDS and COA before approval.
- Written alias or qualifier: Keep the parenthetical text “Turmeric Extract” in the enquiry until current supplier documentation confirms its exact role.
- Written form or source terms: The name explicitly includes Extract. Preserve these terms and ask the supplier to define their analytical or compositional basis.
How to specify Curcumin (Turmeric Extract)
Use numerical acceptance limits and named test methods wherever they matter. The following fields help turn a name-only enquiry into a comparable specification brief.
- Source identity: Specify the scientific source, organism or source part and any origin requirements relevant to the project.
- Concentration basis: Define the extract ratio, marker compound, activity, potency or compositional target and its analytical method.
- Processing and carrier: Confirm extraction or fermentation route, processing solvents, carriers, excipients and standardization basis where applicable.
- Quality controls: Set relevant limits for residual solvents, pesticides, elemental impurities, microbiology, mycotoxins or allergens.
- Commercial scope: Provide required grade, sample and forecast quantity, packaging, storage, destination and supporting-document needs.
Documents and sample review
For a proposed Curcumin (Turmeric Extract) option, request the current product specification and a representative or recent certificate of analysis. Ask which supporting files are applicable and available, such as an SDS, TDS, origin statement, allergen or GMO statement, residual-solvent data, contaminant testing and destination-market compliance documents.
Evaluate documentation and a representative sample against the buyer’s own analytical, formulation, processing, stability, safety and regulatory criteria before bulk approval. Document and sample availability is confirmed for each enquiry.
Comparing Curcumin (Turmeric Extract) quotations
What can make two source-derived offers materially different?
Source species, source part, processing route, marker basis, carrier system and contaminant controls can all change the commercial material. Request these fields explicitly and verify them on current documentation.
Is CAS 458-37-7 enough to approve the material?
No. A CAS number helps screen identity, but it does not define commercial grade, concentration, physical form, impurity limits, test methods, packaging or regulatory support. Compare those fields on the offered specification and COA.
