O-Dianisidine
chemical compound
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 the benzidine rearrangement from o-anisidine.
o-Dianisidine is a precursor to some azo dyes by formation of the bis(diazonium) derivative, which is coupled to diverse aromatic compounds. Some commercial dyes derived from o-dianisidine include C. I. Direct Blue 1, 15, 22, 84, and 98.
o-Dianisidine is also used in assaying activity of peroxidase in lab. The general reaction of a peroxidase is as follows.

Where the ROOR' can be hydrogen peroxide, and the electron donor be o-dianisidine.
Safety
The manufacture and degradation of o-dianisidine, like other benzidene derivatives, has attracted regulatory attention. It is also used as a reagent in biochemistry in testing for peroxides.
The public source identifies “O-Dianisidine” as chemical compound. This brief keeps that definition visible, then builds a research path around O-Dianisidine, chemical and compound.
Why this record matters
A short description can identify a subject without explaining its stakes. For “O-Dianisidine”, the useful work is to connect “chemical compound” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Nov 17, 2025. The linked authority identifier is Q222968. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
