Quality Control

Our Cyclopropanecarboxylic Acid, 1-(Fluorocarbonyl)-, Ethyl Ester (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, GC, NMR, and MS, to ensure identity, purity, and consistency. Certificates of Analysis (COA) with detailed chromatograms and spectral data are provided to support your R&D and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong acids and incompatible organic solvents.
