Quality Control

Our production of Ethyl 3-[[5-(Acetylamino)-4-[(2-Bromo-4,6-Dinitrophenyl)Azo]-2-Methoxyphenyl]Amino]Butyrate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure consistent composition and performance. A detailed Certificate of Analysis (COA) documenting all test results is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be opaque or stored in dark conditions to prevent degradation.
