Quality Control
Our 1H-Pyrazole-4-Carbonyl Chloride, 1-Methyl-5-Propyl- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available for every shipment to support your quality assurance and regulatory needs.
Storage
Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent derivative, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from heat, open flames, and incompatible materials such as bases, alcohols, and amines.
