Quality Control

Our 3-Chloro-2-Methylpropane-1,2-Diol is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the exacting standards required for advanced synthesis. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory documentation.

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). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality. Keep away from incompatible materials such as strong bases and oxidizing agents.
