Quality Control

Our 3-Chloro-2,2-Dimethyl-But-3-Enoic Acid Methyl Ester is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopy (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. This material is moisture-sensitive (hygroscopic) and should be handled under inert atmosphere for prolonged storage to maintain purity.
