TCI C1120 trans-1,2-Cyclohexanediamine (CAS 1121-22-8) is a rigid cyclic diamine whose two primary amino groups sit in a fixed trans arrangement, making it an excellent chelating backbone. It is a classic precursor to salen-type ligands and to a wide range of urea, thiourea, and macrocyclic frameworks used in coordination chemistry and organocatalysis. Both amines are also readily acylated, sulfonylated, or alkylated for further diversification. AMI Scientific supplies 25 mL and 250 mL sizes; handle it in a fume hood and store cool, sealed, and protected from air and moisture.
