Vitamin D3 sourcing overview
For a Vitamin D3 sourcing request, start with the exact catalog name and CAS 67-97-0, then define the commercial grade and measurable acceptance criteria. A shared name or identifier alone does not establish equivalence between supplier offers.
Procurement context: A vitamin-related or nutrient-form name must be matched to the exact chemical form, salt or derivative, potency or assay basis, stereochemistry, carrier system and stability controls.
Product identity and catalog reference
| Product name | Vitamin D3 |
|---|---|
| CAS No. | 67-97-0 |
| Procurement family | Vitamin-related or nutrient-form raw material |
| Verification status | Confirm every catalog value against the current offered specification, SDS and batch documentation. |
Identity details to preserve
- Exact catalog name: Use “Vitamin D3” as the initial requested name and resolve any supplier synonym to the same documented identity.
- CAS screening reference: The catalog associates 67-97-0 with this listing. Verify the number on the offered specification, SDS and COA before approval.
- Fields not defined by the name: The catalog name does not state a complete grade, assay, concentration, impurity profile or physical supply specification. Add those fields to the RFQ.
How to specify Vitamin D3
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.
- Chemical form: Confirm exact vitamin, derivative, salt, stereochemical or hydrate form and relevant identifier.
- Potency or assay: Define potency, assay or active-content basis, units and analytical method.
- Carrier system: Confirm neat material versus beadlet, dispersion or stabilized preparation and list carriers or antioxidants.
- Stability controls: Set water, degradation, light, oxygen, temperature, packaging and shelf-life requirements as applicable.
- Commercial scope: Provide grade, quantity, destination, pack size and market-specific document requirements.
Documents and sample review
For a proposed Vitamin D3 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 Vitamin D3 quotations
Why must the complete chemical form be written explicitly?
Different salts, esters, stereochemical forms and stabilized preparations can have different assay bases, physical properties and documentation. Use the complete form name and potency method.
Is CAS 67-97-0 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.
Request a quotation for Vitamin D3
Send the exact product name “Vitamin D3”, CAS 67-97-0, required grade and acceptance limits, intended professional use, sample and forecast quantity, pack size, destination country, target date, Incoterm if known and required document list. Derreva can then review the enquiry against current supply information and coordinate the appropriate next step.
