Quality Control

Our 3-[(2-Hydroxyethyl)[4-[(6-Methoxybenzothiazol-2-Yl)Azo]-3-Methylphenyl]Amino]Propiononitrile is produced under strict quality management protocols. Every batch undergoes rigorous analytical testing to ensure consistent purity, chromatic properties, and performance. Certificates of Analysis (COA) detailing specifications such as purity (HPLC), melting point, and heavy metal content are available upon request 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 room temperature (15-25°C). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to maintain product integrity.
