Diamine


A diamine is an amine with exactly two amino groups. Diamines are used as monomers to prepare polyamides, polyimides and polyureas. In terms of quantities produced, 1,6-diaminohexane, a precursor to Nylon 6-6, is most important, followed by ethylenediamine.Vicinal diamines (1,2-diamines) are a structural motif in many biological compounds and are used as ligands in organometallic chemistry

Derivatives of ethylenediamine are prominent:

Xylylenediamines are classified as alkylamines since the amine is not directly attached to an aromatic ring.

Three phenylenediamines are known:

Various N-methylated derivatives of the phenylenediamines are known:

Examples with two aromatic rings include derivatives of biphenyl and naphthalene:

Ethylenediamine

Cadaverine

PPD (para-phenylenediamine)
