Quality Control

Our 3-Chloro-4-Methylbenzyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC/HPLC for purity and identity confirmation (IR, NMR), to ensure it meets exacting standards for use in sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under dry conditions. Keep away from strong acids, bases, and oxidizing agents.
