m-Xylene diamine

M-Xylene Diamine (CAS 1477-55-0), also referred to as m-Xylylenediamine or MXDA, is an aliphatic diamine with two primary amine groups attached to a meta-substituted benzene ring. It carries no assigned E-code. The compound is commercially available under several designations including 1,3-Xylylenediamine.

In epoxy resin systems, MXDA functions as a room-temperature curing agent, where its two reactive amine groups form covalent crosslinks with epoxide groups to build a thermoset network. It is also employed in polyamide synthesis, where it reacts with diacids to produce nylon intermediates used in barrier packaging films. In personal care formulations, it serves as a hair dye intermediate.

MXDA is supplied as a technical-grade liquid and falls under REACH registration requirements for supply within the EU. It is classified under HS code 29215900 for customs purposes. Packaging formats typically include drums and IBCs, with documentation available to support regulatory compliance submissions.
