Quality Control

Our 1-(3-Chlorophenyl)-3,5-Dimethyl-1H-Pyrazole-4-Carbaldehyde is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistent performance for your synthetic applications. Certificates of Analysis (COA) with detailed specifications 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 at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to handle and store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after opening the original container. Keep away from heat, sparks, and open flame.
