ECHEMI Editorial Reference

O-phenylenediamine has active chemical properties, being able to have condensation reaction with acid, aldehydes, ketones and other compounds, generating heterocyclic compounds; it can also have oxidation, condensation, substitution and diazotization reaction.

Figure 2 is o-phenylenediamine oxidation.

Figure 3 is o-phenylenediamine condensation reaction. It appears as colorless monoclinic crystal with air and sunlight in the darker. It is slightly soluble in cold water
o-Phenylenediamine is an organic compound with the formula C6H4(NH2)2. This aromatic diamine is an important precursor to many heterocyclic compounds. It is isomeric with m-phenylenediamine and p-phenylenediamine, and is commonly referred to as OPD.

1,2-phenylenediamine appears as colorless monoclinic crystals if pure; technical grade brownish-yellow crystals or a sandy brown solid. Used in manufacture of dyes, photography, organic synthesis.|1,2-phenylenediamine is a phenylenediamine in which the two amino groups are ortho to each other. It has a role as a hydrogen donor. It derives from a hydride of a benzene.
