It is a mixture of three stereoisomers: cis-1,2-diaminocyclohexane and both enantiomers of trans-1,2-diaminocyclohexane. The mixture is a colorless, corrosive liquid, although older samples can appear yellow. It is often called DCH-99 and also DACH. Manufacture The product is available commercially, manufactured by the hydrogenation of o-phenylenediamine. The two trans enantiomers can be resolved by conversion to diastereomeric salts of various chiral acids.Kouklovsky Cyrille (1S,2S)-1,2-Diaminocyclohexane 2014 Encyclopedia of Reagents for Organic Synthesis 1–23 en 10.1002/047084289x.rn00145.pub3 978-0-470-84289-8 Langlois Yves Aguilar Enrique Fernández-García Jesús M.
