Quality Control

Our 3-Bromo-4-Fluorobenzoyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This compound is hygroscopic (moisture-sensitive) and reacts vigorously with water, alcohols, and strong bases. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition from moisture ingress.
