1,1,1,2-Tetrafluoroethane (also known as norflurane (), R-134a, Klea 134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, HFA-134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential and a lower 100-year global warming ...
Freon, when used as an inhalant has been found to have desired effects such as euphoria or intoxication. This has led to some individuals using Freon recreationally in order to achieve these effects. [8] When inhaled, Freon has toxic effects that can have detrimental impacts on various systems in the body.
Automobile manufacturers began phasing in R-134a around 1993 [citation needed]. When older units leak or require repair involving removal of the refrigerant, retrofitment to a refrigerant other than R-12 (most commonly R-134a) is required in some jurisdictions. The United States does not require such conversion.

This powerful deodorant from Mitchum really packs a punch. As the name suggests, it provides three forms of odor defense, reducing odor produced by warmth, stress, and activity.
It is a zeotropic blend of difluoromethane (R-32), pentafluoroethane (R-125), and 1,1,1,2-tetrafluoroethane (R-134a). Difluoromethane serves to provide the heat capacity, pentafluoroethane decreases flammability, tetrafluoroethane reduces pressure. [1] R-407C cylinders are colored burnt orange.
Some people may carry a gene variation that helps them avoid body odor. Some people don't have body odor, even without deodorant. Here's why — and what we can learn from them.
For example, R-134a has 2 carbon atoms, 2 hydrogen atoms, and 4 fluorine atoms, an empirical formula of tetrafluoroethane. The "a" suffix indicates that the isomer is unbalanced by one atom, giving 1,1,1,2-Tetrafluoroethane. R-134 (without the "a" suffix) would have a molecular structure of 1,1,2,2-Tetrafluoroethane.
