Quality Control

Our Benzoyl Chloride, 5-Cyano-2-Hydroxy- (9Ci) is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity suitable for research and development applications. We provide comprehensive analytical data, including HPLC purity, identity confirmation (IR, NMR), and impurity profiling. A Certificate of Analysis (COA) detailing all specifications is available for every batch upon request, supporting your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from incompatible materials such as strong bases, strong oxidizing agents, and alcohols.
