Quality Control

Our Cyanic Acid, 4-Ethenyl-2,6-Dimethylphenyl Ester (9Ci) is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and structural confirmation, to ensure it meets the high standards required for research and industrial applications. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong acids, bases, and oxidizing agents.
