Quality Control

Our 2,2,3,3,4,4,4-Heptafluorobutyl Isocyanate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including assay by GC or HPLC and impurity profiling, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee compliance with your research and production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize volatility and degradation. Due to its highly volatile and moisture-sensitive nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening. Keep away from strong bases, alcohols, amines, and moisture.
