R32 (Difluoromethan), R-32, Methylene fluoride, Methylene difluoride, Freon 32, Carbon fluoride hydride, Genetron 32, HFC-32, HFC32, is an organic compound of the dihalogeno-alkane variety. It is based on methane, except that two of the four hydrogen atoms have been replaced by fluorine atoms. Hence the formula is CH₂F₂ instead of CH₄ for normal methane.
