Quality Control

Our production of Benzoyl Chloride, 5-Formyl-2-Hydroxy- (9Ci) adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity suitable for sensitive synthetic applications. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting identity, purity, and relevant physical parameters.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and amines.
