Quality Control

Our production of Benzoyl Chloride, 4-Isocyanato-3-Methyl- (9Ci) adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay (HPLC), identity confirmation (IR, NMR), and impurity profiling, to ensure consistency and high purity suitable for research and industrial synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its moisture-sensitive (hygroscopic) nature, containers 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, open flames, and incompatible materials such as strong bases, alcohols, and amines.
