Diaminotoluenes

In chemistry, the diaminotoluenes form a group of aromatic compounds that are derived from both toluene and phenylenediamines . The structure consists of a benzene ring with an attached methyl group  (-CH ₃ ) and two amino groups  (-NH ₂ ) as substituents . Their different arrangement results in six constitutional isomers with the empirical formula C ₇ H ₁₀ N ₂ .
