1,3-bis(aminomethyl)cyclohexane (1,3-BAC) are a collection of organic compounds with the formula C6H10(CH2NH2)2.
The compounds belong to the sub class cycloaliphatic amine.
Their key use is as an epoxy resin curing agent.
[1] The primary route of manufacture is by catalytic hydrogenation of m-xylylenediamine usually called MXDA.
However, the presence of the amino group also means it can be used in polyurethane chemistry by reacting with isocyanates.
