L-Carnosine sourcing overview
Derreva lists L-Carnosine under CAS 305-84-0 for specification-led B2B sourcing and quotation review. The catalog identifier is a screening reference; approval should rely on the exact offered identity, current specification, batch documentation and buyer acceptance criteria.
Procurement context: An amino-acid or biochemical listing requires the exact molecular, salt and stereochemical form, assay basis, related-substance profile and suitable storage conditions.
Product identity and catalog reference
| Product name | L-Carnosine |
|---|---|
| CAS No. | 305-84-0 |
| Procurement family | Amino-acid or biochemical 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 “L-Carnosine” as the initial requested name and resolve any supplier synonym to the same documented identity.
- CAS screening reference: The catalog associates 305-84-0 with this listing. Verify the number on the offered specification, SDS and COA before approval.
- Written form qualifier: The written qualifier “L-” is identity-relevant and should not be removed when comparing documents or quotations.
How to specify L-Carnosine
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.
- Complete identity: Confirm exact molecular name, D-, L-, DL- or other stereochemical designation, salt form and relevant identifier.
- Assay basis: Define assay or active-content basis, units, dry or as-is basis and analytical method.
- Related substances: Set stereochemical purity, related compounds, water, residual solvents and other critical impurity limits.
- Physical and stability: Specify physical form, solubility or particle criteria, packaging, storage and shelf-life requirements.
- Commercial scope: Provide grade, sample and forecast quantity, destination and required supporting documents.
Documents and sample review
For a proposed L-Carnosine 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 L-Carnosine quotations
Why should stereochemical and salt form be explicit?
Different stereochemical or salt forms are not interchangeable specification names. They can change formula basis, assay calculations and physical behaviour, so the complete form should appear on the RFQ and offered documents.
Is CAS 305-84-0 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 L-Carnosine
Send the exact product name “L-Carnosine”, CAS 305-84-0, 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.
