Quality Control

Our 1,3-Dichlorobenzene is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive quality assurance, with products tested against rigorous in-house specifications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is available for every batch upon request, supporting your compliance and quality documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids and strong oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to prevent moisture absorption and volatilization.
