Quality Control

Our (4-Methoxyphenyl)Methyl 2,2-Dimethyl-3-(2-Methylprop-1-Enyl)Cyclopropane-1-Carboxylate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets exacting standards for fine chemical intermediates. A comprehensive Certificate of Analysis (COA) detailing purity, enantiomeric excess (where applicable), and impurity profiles is provided with each shipment to guarantee traceability and consistency for your synthesis processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is light-sensitive and should be stored away from direct light. It is also compatible with strong acids and organic solvents but should be kept under an inert atmosphere (e.g., nitrogen) to minimize potential oxidation during long-term storage. Keep away from heat, sparks, and open flames.
