Quality Control

Our production of 5-[[4-Chloro-6-(Phenylamino)-1,3,5-Triazin-2-Yl]Amino]-4-Hydroxy-3-[(2-Sulphophenyl)Azo]Naphthalene-2,7-Disulphonic Acid adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and compliance with industry specifications. Certificates of Analysis (COA) detailing all critical parameters are available upon request to support your quality assurance processes.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed and stored under conditions of low humidity to prevent degradation and clumping.
