Quality Control

Our n-Butyl Heptafluorobutyrate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to meet exacting customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids, bases, and oxidizing agents. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is 2-8°C for long-term stability.
