Quality Control

Our 1H-1,2,3-Triazole-4,5-Dicarbonyl Dichloride, 1-Methyl- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high purity and consistent reactivity, which are critical for sensitive synthetic applications. Comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity. Recommended long-term storage temperature is 2-8°C.
