Quality Control

Our 1-(1-Chloroethyl)-2-Methylbenzene is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, confirming compliance with agreed specifications. Our quality system supports cGMP standards for pharmaceutical applications where required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to exclude moisture. Keep away from heat, sparks, and open flame.
