(1S)-(+)-trans-1,2-Diaminocyclohexane (also named (1S)-(+)-trans-1,2- Cyclohexanediamine; (1S,2S)-1,2-cyclohexanediamine; (1S,2S)-1,2-Diaminocyclohexane), together with its (1R, 2R) enantiomer, allows excellent levels of asymmetric induction in many reactions, produced by resolution of trans-1,2-diaminocyclohexane.
It is an off-white powder or pale-yellow oil, depending on the temperature, which could be dissolved in most of polar organic solvent.
UCHEM has been manufacturing (1S)-(+)-trans-1,2-Diaminocyclohexane and its enantiomer ((1R)-(+)-trans-1,2-Diaminocyclohexane, and other N-substituted derivatives for many years, who could guarantee both chemical purity and optical purity over 99%.
