m-Phenylenediamine, also called 1,3-diaminobenzene, is an organic compound with the formula C6H4(NH2)2. It is an isomer of o-phenylenediamine and p-phenylenediamine. This aromaticdiamine is a colourless solid that appears as needles, but turns red or purple on exposure to air due to formation of oxidation products.[3] Samples often come as colourless flakes and may darken in storage.
m-Phenylenediamine is used in the preparation of various polymers including aramid fibers, epoxy resins, wire enamel coatings and polyurea elastomers. Other uses for m-phenylenediamine include as an accelerator for adhesive resins, and as a component of dyes for leather and textiles. Basic Brown 1, Basic Orange 2, Direct Black 38, and Developed Black BH. In hair-dying, m-phenylenediamine is a "coupling agent", used to produce blue colors.[5]
