Quality Control

Our 2-Chloro-1,1,1,3-Tetrafluorobut-2-Ene is produced and handled under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay (by GC), identity confirmation (by FT-IR/GC-MS), and impurity profiles. Our quality commitment aligns with cGMP principles for pharmaceutical intermediates and ISO standards for industrial chemical production.

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 purity. Recommended storage temperature is 2-8°C for long-term stability, though short-term storage at controlled room temperature (15-25°C) is acceptable.
