o-Dianisidine is an organic compound with the formula [(CH3O)(H2N)C6H3]2. A colorless or white solid, it is a bifunctional compound derived via thebenzidine rearrangement fromo-anisidine.
o-Dianisidine is a precursor to someazo dyes by formation of the bis(diazonium) derivative, which is coupled to diverse aromatic compounds. Some commercial dyes derived fromo-dianisidine include C. I.Direct Blue 1,15,22,84, and98.[1]
o-Dianisidine is also used in assaying activity ofperoxidase in lab. The general reaction of a peroxidase is as follows.
Where the ROOR' can behydrogen peroxide, and the electron donor beo-dianisidine.
The manufacture and degradation ofo-dianisidine, like other benzidene derivatives, has attracted regulatory attention.[2] It is also used as a reagent in biochemistry in testing forperoxides.
