o-Toluidine is used or applied in different circumstances. It is used the most for dye, especially for coloring hair. The other usages of o-toluidine are specific determination of glucose in blood and the most recent one, the separation of toxic metal ions, which is still in the research phase.

o-Toluidine has been used as a dye precursor since the 19th century, when synthetic dye was produced.In the years that , the aromatic amine functioned as a precursor of many dyes and pigments for consumer goods. But when the carcinogenicity of o-toluidine for animals was recognized, and that it potentiality could be carcinogenic for humans, the production of o-toluidine and its use in dye manufacturing has been largely banned in the Western world and in many parts of the East. But there are still a few dyes that are based on this compound. The most known compounds are petroleum products and yellow organic pigments. It is also an essential compound in the production of 4-chloro-o-toluidine and 4-amino-2′,3-dimethylazobenzene, which are also dyes.
