Quality Control

Our 1,1-Difluorobutene is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including GC and NMR analysis, to verify identity and assay. A detailed Certificate of Analysis (COA) documenting purity, physical properties, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

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 open flames. Recommended storage temperature is 2-8°C to maintain stability. Keep container tightly sealed when not in use to prevent evaporation and potential contamination.
