⚗️ Chemical Overview

1,3-phenylenediamine appears as colorless or white colored needles that turn red or purple in air. Melting point 64-66 C. Density 1.14 g / cm3. Flash point 280 F. May irritate skin and eyes. Toxic by skin absorption, inhalation or ingestion. Used in aramid fiber manufacture, as a polymer additive, dye manufacturing, as a laboratory reagent, and in photography. 1,3-phenylenediamine is a phenylenediamine taht is benzene substituted at positions 1 and 3 with amino functions. On the basis of the animal and clinical data included in this report, the CIR Expert Panel concludes that m-Phenylenediamine and m-Phenylenediamine Sulfate are safe for use in hair dyes at concentrations of up to 10%.
