C6H6N2

C6H6N2 is the molecular formula for several chemical compounds, all of which are isomers. This means they share the same number of carbon, hydrogen, and nitrogen atoms but differ in their structural arrangement. The most common isomer with this formula is phenylenediamines, which are aromatic diamines. Phenylenediamines exist in three isomeric forms: ortho-phenylenediamine (o-phenylenediamine), meta-phenylenediamine (m-phenylenediamine), and para-phenylenediamine (p-phenylenediamine). Each of these isomers has two amino groups attached to a benzene ring, with the positions of the amino groups determining the specific isomer.

Ortho-phenylenediamine has the amino groups on adjacent carbon atoms of the benzene ring. Meta-phenylenediamine has the amino groups on carbon atoms separated by one other carbon atom. Para-phenylenediamine has the amino groups on opposite sides of the benzene ring. These compounds are typically solids at room temperature and exhibit varying degrees of solubility in water and organic solvents. Their chemical properties are influenced by the presence of both the aromatic ring and the amino groups, making them reactive in various organic synthesis processes. They find applications in the production of dyes, polymers, pharmaceuticals, and as antioxidants.
