For sourcing managers in the fine chemical and pharmaceutical sectors, finding high-assay aromatic aldehydes means protecting your synthetic yields from unexpected polymeric side-reactions. Our 4-diethylaminobenzaldehyde CAS 120-21-8 is manufactured using specialized purifying distillation steps to eliminate trace isomer contamination, ensuring seamless integration into your condensation or condensation-copolymerization pipelines.
- Verified High Assay (≥ 99.0% by HPLC): Minimizes free amine residues and unreacted precursors that cause discoloration or reduce the brilliance of synthesized dyes.
- Controlled Melting Point Stability: Matches strict crystalline standards (73°C – 75°C), ensuring rapid dissolving profiles in ethanol, ether, and chloroform without leaving insoluble particulate matter.
- Enhanced Oxidation Resistance: Packaged under inert nitrogen padding to prevent ambient oxygen from degrading the reactive aldehyde group into carboxylic acid during maritime transit and warehousing.
- Global Regulatory and Audit Support: Full traceability with complete Certificate of Analysis (COA), safety profiles (SDS), and batch production records tailored for strict industrial supply chains.
Product Packaging
Our high-purity 4-diethylaminobenzaldehyde raw material delivers predictable performance across diverse cutting-edge chemical manufacturing workflows:
- Laser and Functional Dye Industry: Serves as a vital structural block for synthetic cyanine, styryl, and azo dyes requiring specific near-infrared absorption or intense fluorescence.
- Diagnostic Reagents & Biochemistry: Utilized in laboratory clinical assays to test for specific amino acids, urea derivatives, and specialized chemical screening complexes.
- Pharmaceutical Intermediates: Acts as a fundamental reactant in organic condensation loops for constructing customized bio-active heterocyclic molecules.
- Photo-curable Polymers: Embedded into specialty printing plates and photoresist matrices due to its excellent cross-linking support when exposed to specific light wavelengths.
Logistics, Packaging & Custom Commercial Handling
- Packaging Framework: Standard delivery in 25kg fiber drums lined with double-layer anti-static PE bags, or customizable small-pack configurations for pilot labs.
- Storage Best Practices: Keep sealed tightly under nitrogen or dry environment inside dark, cool, well-ventilated storage rooms away from light and oxidizers.
- Document Transparency: Each global shipment provides verified tracking, batch COA, and international custom-cleared hazard classification paperwork.
FAQ
Because 4-diethylaminobenzaldehyde is sensitive to light and air, our facility seals each container with light-shielding materials and uses vacuumized nitrogen-purged inner bagging. This keeps the moisture levels well under 0.5% and stops auto-oxidation, ensuring the powder stays free-flowing and beige upon arrival.
We offer a complete documentation package for your compliance audits, including spectroscopic identification data (NMR/IR), validated HPLC chromatograms, and a clear manufacturing flow chart indicating raw material origin.
