Quality Control

Our 4,4-Dichloro-1,1,1,3,3-Pentafluorobutane is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopy (NMR, IR), to ensure high purity and consistent composition. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, identity, and impurity profiles. We adhere to relevant industry standards and can support GMP or ISO 9001 compliance documentation as required for critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources, open flames, and incompatible materials such as strong bases and reactive metals. Due to its highly volatile nature, ensure containers are kept upright and sealed when not in use. Recommended storage temperature is between 2°C and 25°C.
