Quality Control

Our 3,5-Dimethylbenzoyl Chloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay by titration and impurity profile analysis by GC/HPLC, to ensure high purity and consistency. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment. We adhere to cGMP standards where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This material is hygroscopic (moisture-sensitive) and reacts vigorously with water, strong bases, and alcohols. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture absorption. Store away from incompatible materials such as strong acids, organic solvents, and oxidizing agents.
