Quality Control

Our 3,5-Dimethyl-1-Phenyl-1H-Pyrazole-4-Carbonyl Chloride is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure high purity and consistent performance. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specifications and test results to support your quality assurance and regulatory compliance 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 and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong bases and oxidizing agents.
