Quality Control

Our 4-Phenoxyphenyl Isocyanate is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment to guarantee compliance with your specifications and industry standards.

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, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation from moisture.
