Quality Control

Our 1-[(p-Tolyl)Methyl]Cyclopropanecarbonyl Chloride is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR/IR for structural confirmation, to ensure it meets the high standards required for research and process chemistry. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties as a strong acid/organic solvent, hygroscopic (moisture-sensitive), and highly volatile nature, it must be stored in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Keep away from heat, sparks, open flames, and incompatible materials such as bases, alcohols, and amines.
