Quality Control

Our Cyanic Acid, C,C'-(Methylenedi-4,1-Phenylene) Ester is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including chromatography and spectroscopy, to confirm identity and meet precise specifications. Certificates of Analysis (COA) detailing purity, moisture content, and other critical parameters are available for every batch upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed when not in use to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
