Quality Control

Our 1H-Imidazole-5-Carbonyl Chloride, 2-Chloro-1-Methyl- (9Ci) is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the exacting standards required for research and process chemistry. Comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation and moisture uptake. Keep away from heat, sparks, and open flame.
