Diamine

Amine oxidase is an enzyme involved in the metabolism of histamine.

Ethylenediamine (abbreviated as en when a ligand) is the organic compound with the formula C2H4(NH2)2. This colorless liquid with an ammonia-like odor is a strongly basic amine.

Hexamethylenediamine is the organic compound with the formula H2N(CH2)6NH2. The molecule is a diamine, consisting of a hexamethylene hydrocarbon chain terminated with amine functional groups.

M-Phenylenediamine, also 1,3-diaminobenzene, is an aromatic amine, with formula C6H4(NH2)2. It is an isomer of o-phenylenediamine and p-phenylenediamine.

Isophorone diisocyanate (IPDI) is an organic compound in the class known as isocyanates. More specifically, it is an aliphatic diisocyanate. It is produced in relatively small quantities, accounting for (with hexamethylene diisocyanate) only 3.4% of the global diisocyanate market in the year 2000.
