Quality Control

Our 3,3,4,4,4-Pentafluoro-2-Butanol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed under a dry inert atmosphere to prevent degradation. Keep away from strong bases and fluorides.
