Trifluoromethane is a colorless, odorless gas that is also known as carbon trifluoride or Freon-13. It is commonly used as a refrigerant, propellant, and in pharmaceutical and chemical manufacturing. There are several synonyms for trifluoromethane, including Freon CF3, R-13, Halon 23, and carbon trifluoride. These terms are often used interchangeably in scientific literature and industry-related discussions. However, it is important to note that the use of certain forms of trifluoromethane has been regulated due to its effects on the environment, particularly its contribution to global warming. As such, alternative substances such as hydrofluorocarbons (HFCs) are being used as substitutes in specific applications.
