Quality Control

Our 3-Phenoxyphenyl Isocyanate is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes comprehensive analytical testing, including chromatography and spectroscopy, to verify identity and meet precise specifications. A Certificate of Analysis (COA) detailing all quality parameters is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation from moisture ingress.
