Quality Control

Our 2-(4-Bromo-2-Chlorophenoxy)Butanoyl Chloride is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to confirm identity and quantify purity. Certificates of Analysis (COA) detailing all specifications are provided with every shipment and are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its nature as a strong acid/organic solvent, it should be kept away from moisture, heat, and incompatible materials such as bases, alcohols, and oxidizing agents. Use appropriate corrosion-resistant storage equipment.
