Quality Control

Our 2-Chloromethyl-2-Methyl-1,3-Dimethoxypropane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR), to ensure high chemical purity and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing purity, identity, and impurity profiles 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 a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
