Quality Control

Our trans-1-Fluoro-1-Propene is produced and handled under stringent quality management protocols. Each batch is analyzed using advanced techniques including Gas Chromatography (GC) and NMR to ensure high chemical purity and isomeric integrity. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee reliable performance in your sensitive applications.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area away from heat sources and ignition points. For long-term stability, storage under an inert atmosphere (e.g., nitrogen or argon) in a sealed cylinder or pressure-rated vessel is recommended. Keep container tightly sealed when not in use.
