Quality Control

Our Difluorophenylmethyl Isocyanate is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including chromatography and spectroscopy, to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay and impurity profiles to meet your specific R&D or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile and moisture-sensitive nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) at temperatures between 2°C and 8°C for long-term stability. Keep away from strong bases and open flames.
