Quality Control

Our 1,1,2-Trifluoro-1-pentene is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided with every shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile nature, keep container tightly sealed when not in use. Recommended storage temperature is 2-8°C (refrigerated) for long-term stability. Keep away from strong bases and incompatible materials.
