Quality Control

Our Benzoyl Isocyanate, 4-Methyl- (9Ci) is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay (HPLC), identity confirmation (IR), and impurity profiling, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) documenting purity and specifications are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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 degradation by atmospheric moisture.
