Quality Control

Our Vinyl Heptafluorobutyrate is manufactured under stringent controls to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing including GC, NMR, and FTIR. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

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 nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature is 2-8°C for extended stability.
