|Section2= }} Bromochlorofluoromethane or fluorochlorobromomethane, is a chemical compound and trihalomethane deriative with the chemical formula CHBrClF. As one of the simplest possible stable chiral compounds, it is useful for fundamental research into this area of chemistry.〔Kenneth L. Berry and Julian M. Sturtevant. Fluorochlorobromomethane. ''Journal of the American Chemical Society'' 1942; 64(7): 1599-1600. DOI: 10.1021/ja01259a031〕 However its relative instability to hydrolysis,〔Thomas L. Gilchrist. Comprehensive Organic Functional Group Transformations. Volume 6. Synthesis: Carbon with Three or Four Attached Heteroatoms. p228. Pergamon / Elsevier, 1995. ISBN 0-08-042704-9〕 and lack of suitable functional groups, made separation of the enantiomers of bromochlorofluoromethane especially challenging,〔Michael K. Hargreaves and Borzoo Modarai. An optically active haloform: (+)-bromochlorofluoromethane. ''J. Chem. Soc. D''; 1969: 16-16. DOI: 10.1039/C29690000016〕 and this was not accomplished until almost a century after it was first synthesised, though it has now been done by a variety of methods.〔Canceill J, Lacombe L, Collet A.
