m-Xylylenediamine is an organic compound with the formula C<sub>6</sub>H<sub>4</sub>(CH<sub>2</sub>NH<sub>2</sub>)<sub>2</sub>. A colorless oily liquid, it is produced by hydrogenation of isophthalonitrile.
m-Xylylenediamine (MXDA) is used in a variety of industrial applications including amine based curing agents for epoxy resins which may then be formulated into coatings, adhesives, sealants, and elastomers.
m-Xylylenediamine undergoes the Sommelet reaction to give isophthalaldehyde.
Exposure to m-xylylenediamine may occur by inhalation, skin contact, eye exposure, or ingestion. It can cause chemical burns, tissue damage, delayed pulmonary edema, shock, and skin sensitization. Symptoms of inhalation include a burning sensation in the respiratory tract, cough, sore throat, labored breathing, and dyspnea(shortness of breath). It is also flammable and produces toxic fumes when burned. m-Xylylenediamine reacts with acids, acid chlorides, and acid anhydrides.
