Quality Control

Our production of Cyclopropanecarboxylic Acid, 3-(Chlorocarbonyl)-2,2-Dimethyl-, Methyl Ester, cis- (9Ci) adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with customer specifications and internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area 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) after opening to prevent degradation. Keep away from strong acids and incompatible organic solvents.
