Quality Control

Our 1-Chloro-2,3,3,4,4,5,5-Heptafluorocyclopent-1-Ene is produced under strict quality management protocols. Every batch undergoes comprehensive analytical testing, including GC, GC-MS, and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and available upon request. We support custom purity grades to meet specific R&D and production requirements.

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 upright and sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability, though short-term storage at controlled room temperature (15-25°C) is acceptable.
