Difluoromethane, also known as HFC-32, is a colorless gas with a slightly sweet odor. It is a type of hydrofluorocarbon (HFC) and is primarily used as a refrigerant in air conditioning systems and refrigeration applications. Its chemical formula is CH2F2, and it has a low global warming potential compared to other refrigerants. This compound is produced through chemical processes and is valued for its efficiency in heat transfer. Difluoromethane is also used in the manufacturing of foam products and as a propellant in aerosol applications. Safety measures are important when handling it, as it can be harmful if inhaled in large quantities.
