Description :

Overview of M-Phenylenediamine

M-Phenylenediamine (1,3-Diaminobenzene) is an aromatic diamine used as a curing agent for epoxy resins, a dye intermediate, and a chemical building block in polymer and specialty chemical production.

Known for its two amino groups in meta positions providing excellent reactivity and crosslinking capability, M-Phenylenediamine is widely used in composites manufacturing, producing aramid fibers, dye synthesis, and industrial polymer applications.

This compound appears as a white to light brown crystalline solid that darkens on exposure to air and light. Its diamine structure provides versatile reactivity for polymerization, condensation reactions, and forming heterocyclic compounds.

Related products include P-Phenylenediamine, O-Phenylenediamine, and other aromatic diamines used in polymer chemistry and industrial applications.
