Difluoromethane, also called difluoromethylene, HFC-32 Methylene Fluoride or R-32, is an organic compound of the dihalogenoalkane variety. It has the formula of CH₂F₂. It is a colorless gas in the ambient atmosphere and is slightly soluble in the water, with a high thermal stability. Difluoromethane is commonly used in endothermic processes such as refrigeration or air conditioning.
