Quality Control

Our Benzoyl Chloride, 2-Hydroxy-3-Methoxy- (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets the stringent requirements of our global clientele in research and regulated industries. Certificates of Analysis (COA) documenting all critical parameters are available upon request 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 a controlled room temperature (typically 15-25°C). This compound is hygroscopic (moisture-sensitive) and reacts with strong acids/organic solvents; therefore, it must be kept under an inert atmosphere (e.g., nitrogen or argon) in its original packaging to prevent decomposition. Keep away from heat, open flames, and incompatible materials such as bases, alcohols, and amines.
