Quality Control

Our 1H-Pyrazole-3,5-Dicarbonyldichloride(9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure high purity and consistent performance. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available upon request for quality assurance and regulatory compliance.

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). This material is hygroscopic (moisture-sensitive) and should be handled under a dry inert atmosphere to prevent decomposition. Keep away from strong acids and organic solvents.
