Quality Control

Our production of 2-[(2,5-Dichlorophenyl)Azo]-n-(6-Ethoxy-2-Benzothiazolyl)-3-Oxo-Butanamide adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity. All materials undergo comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
