Quality Control

Our production of Phenol, 5-Isocyanato-2-Methyl- (9Ci) adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications. We support cGMP and ISO 9001 aligned practices for traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize volatility and degradation. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) and keep away from heat, sparks, and open flames. Keep container tightly sealed when not in use to prevent moisture ingress and polymerization.
