Quality Control

Our Heptafluorobutanol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistency. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing all specification parameters. Our quality commitment aligns with cGMP and ISO 9001 standards to meet the stringent requirements of our global B2B clientele.

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 and bases. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability, though short-term storage at 15-25°C is acceptable.
