Quality Control

Every batch of 2-Chloro-4,5-Difluorobenzoyl Chloride is manufactured and tested under a strict quality management system. We guarantee high chemical purity and consistency, supported by comprehensive analytical testing including GC, HPLC, and NMR. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to ensure compliance with your project specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at 15-25°C. Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong bases, oxidizing agents, and sources of ignition.
