Quality Control

Our 1-(2,3-Dimethoxyphenyl)But-3-Enyl 2,2-Dimethyl-3-(2-Methylprop-1-Enyl) Cyclopropane-1-Carboxylate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure compliance with exacting R&D and process chemistry standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Keep away from heat, sparks, and open flame. Due to its light-sensitive and easily oxidized nature, minimize exposure to air and light during handling.
