Quality Control

Our 3,5-Dichloro-2-Fluorotoluene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC/HPLC for purity and identity confirmation, to ensure it meets the high standards required for synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical properties is provided with every shipment.

Storage

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