Fluorescent Brightening Agent 134 (Optical Brightener CF) sourcing overview
This Fluorescent Brightening Agent 134 (Optical Brightener CF) page organizes the identity and procurement fields needed for a clear B2B enquiry. CAS 3426-43-5 is the catalog reference, while grade, assay basis, physical format, impurity limits and supporting evidence must be confirmed for the specific offer.
Procurement context: An optical specialty material should be matched by exact commercial or chemical identity, active content, colour or optical test basis, solubility or dispersibility and application-specific acceptance criteria.

Identity details to preserve
- Exact catalog name: Use “Fluorescent Brightening Agent 134 (Optical Brightener CF)” as the initial requested name and resolve any supplier synonym to the same documented identity.
- CAS screening reference: The catalog associates 3426-43-5 with this listing. Verify the number on the offered specification, SDS and COA before approval.
- Written alias or qualifier: Keep the parenthetical text “Optical Brightener CF” in the enquiry until current supplier documentation confirms its exact role.
How to specify Fluorescent Brightening Agent 134 (Optical Brightener CF)
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 chemical or commercial designation, identifier and whether aliases refer to the same offered grade.
- Assay or active basis: Define assay, active content or solids and the named reporting method.
- Optical criteria: State the required colour, absorption, fluorescence or comparative performance method and acceptance range.
- Physical criteria: Specify supply form, particle size, solubility or dispersibility, moisture and process-relevant impurity limits.
- Commercial scope: Provide grade, quantity, packaging, storage, destination and technical-document requirements.
Documents and sample review
For a proposed Fluorescent Brightening Agent 134 (Optical Brightener CF) 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 Fluorescent Brightening Agent 134 (Optical Brightener CF) quotations
Can optical grades be compared from the trade name alone?
Not reliably. Commercial designations can cover different concentrations, salt forms or test bases. Compare the identity, active basis and optical method stated on the offered specification.
Is CAS 3426-43-5 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.
