Quality Control

Our Benzoyl Chloride, 4-(Methoxyazo)- is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and precise titration methods, to ensure it meets exacting R&D and pilot-scale requirements. Certificates of Analysis (COA) with full traceability are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
