1,1-Difluoroethane is a colorless gas at room temperature, commonly used as a refrigerant and propellant in aerosol products. Its chemical formula is C2H4F2, indicating it contains two carbon atoms, four hydrogen atoms, and two fluorine atoms. This compound is part of the hydrofluorocarbon (HFC) family and is known for its low ozone depletion potential. However, it is a greenhouse gas, contributing to climate change. Due to its properties, 1,1-Difluoroethane is often favored in applications requiring a less harmful alternative to older refrigerants.
