1,3-Bis(aminomethyl)cyclohexane

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.

Manufacture
It has been produced commercially as part of a mixture with the 1,4 derivative. The primary route of manufacture is by catalytic hydrogenation of m-xylylenediamine usually called MXDA.

Uses
Like most amines it maybe used as an epoxy curing agent. However, the presence of the amino group also means it can be used in polyurethane chemistry by reacting with isocyanates. In this case a polyurea would be produced. It may also be reacted with phosgene (phosgenation) to produce an isocyanate.

Safety
It is corrosive with a Packing Group I designation.
