Quality Control

Every batch of our 2-[Ethyl[3-Methyl-4-[(5-Nitro-2,1-Benzisothiazol-3-Yl)Azo]Phenyl]Amino]Ethanol undergoes rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Our quality assurance protocols are designed to meet the stringent requirements of industrial and research applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality management systems.

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, sparks, and open flame. Due to its light-sensitive nature, containers should be opaque or stored in dark conditions to prevent degradation.
