Quality Control

Our (2E)-3-(1-Ethyl-3-Methyl-1H-Pyrazol-4-Yl)Acryloyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing all 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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from strong acids and incompatible organic solvents.
