Quality Control
Our 4-Bromo-3-Chlorobenzoyl 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 purity, identity, and impurity profiles are provided with every shipment to guarantee compliance with your specific research or production requirements.
Storage
Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and reacts with water and alcohols; containers must be kept tightly sealed under an inert atmosphere such as nitrogen or argon. Keep away from strong bases, amines, and oxidizing agents.
