Quality Control

Our 1,1-Difluorocyclopentane is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including gas chromatography (GC) for assay and purity, identity confirmation by FT-IR or NMR, and control of key impurities. A Certificate of Analysis (COA) detailing all test results 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 place, away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C (refrigerated) for long-term stability. Keep container tightly sealed when not in use to prevent evaporation and potential ingress of moisture.
