Quality Control

Our 1,3,3-Trimethyl-2-[[Methyl[4-(Phenylazo)Phenyl]Hydrazono]Methyl]-3H-Indolium Methyl Sulphate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request, providing full traceability and compliance assurance for your quality protocols.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed when not in use to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
