Description

1,1-Dichloro-2,2-Difluoroethane is a halogenated hydrocarbon with a unique combination of chlorine and fluorine atoms, making it a valuable intermediate and specialty solvent. Its primary commercial value lies in its role as a precursor in the synthesis of fluorinated compounds, including refrigerants, propellants, and pharmaceutical intermediates. This chemical is essential for manufacturers in the refrigeration, agrochemical, and advanced materials sectors seeking to develop next-generation fluorinated products.

Application

• Chemical Synthesis Intermediate: A key building block for manufacturing hydrofluoroolefins (HFOs) and other next-generation fluorinated refrigerants with low global warming potential.
• Pharmaceutical Manufacturing: Used as a fluorinating agent or intermediate in the synthesis of active pharmaceutical ingredients (APIs) that contain fluorine for enhanced metabolic stability and bioavailability.
• Agrochemical Production: Serves as a precursor for creating fluorinated pesticides and herbicides, where the fluorine atom improves efficacy and environmental profile.
• Specialty Solvent: Employed in specific applications requiring a solvent with unique polarity and volatility characteristics for coatings or precision cleaning.
• Polymer & Material Science: Acts as a monomer or modifying agent in the production of specialty fluoropolymers with enhanced chemical resistance and thermal stability.
• Fire Extinguishing Agents: A potential component in the formulation of clean, effective fire suppression systems (halon replacements).

Quality Control

Every batch of 1,1-Dichloro-2,2-Difluoroethane is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards and customer-specific requirements through rigorous analytical protocols. A comprehensive Certificate of Analysis (COA), detailing purity, identity, and impurity profiles as determined by GC, GC-MS, and NMR, is provided with each shipment to guarantee consistent quality and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources, ignition points, and incompatible materials. Due to its highly volatile nature, containers must be kept tightly sealed when not in use to prevent evaporation and maintain purity. Recommended storage temperature is 2-25°C.
