Quality Control

Our 1-Amino-5-Methyl-1H-Benzotriazole is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency, meeting the high standards required for research and industrial synthesis. Certificates of Analysis (COA) with detailed specifications are provided for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its light-sensitive nature and propensity for oxidation, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
