Benzophenone-4 sourcing overview
Derreva lists Benzophenone-4 under CAS 4065-45-6 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: The catalog name identifies a specific commercial material, but it does not define a universal grade, purity, composition, physical form or approved use. Match the complete offered specification to the buyer requirement.
Product identity and catalog reference
| Product name | Benzophenone-4 |
|---|---|
| CAS No. | 4065-45-6 |
| Procurement family | Specialty 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 “Benzophenone-4” as the initial requested name and resolve any supplier synonym to the same documented identity.
- CAS screening reference: The catalog associates 4065-45-6 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 Benzophenone-4
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.
- Exact identity: Confirm the preferred chemical or ingredient name, CAS or other identifier, and every written salt, derivative, source or stereochemical qualifier.
- Grade and assay: State the required grade, assay or purity basis, acceptance range and named analytical method.
- Impurity profile: Define the related substances, water, residual solvents, elemental impurities, microbiological limits or other controls relevant to the project.
- Physical criteria: Specify the required supply form and any particle-size, viscosity, density, solubility, colour or handling criteria that affect processing.
- Commercial scope: Provide sample and forecast quantity, pack size, storage, destination, timing, Incoterm and document requirements.
Documents and sample review
For a proposed Benzophenone-4 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 Benzophenone-4 quotations
Why should quotations be compared against a full specification?
The same short product name can cover different grades, assay methods, physical forms and impurity limits. A line-by-line specification comparison makes the quoted identity and quality basis clear.
Is CAS 4065-45-6 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 Benzophenone-4
Send the exact product name “Benzophenone-4”, CAS 4065-45-6, 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.
