O-Toluidine

O-Toluidine, also known as 2-toluidine, is an organic compound that is a colorless or light yellow oily liquid at room temperature. It is slightly soluble in water, soluble in ethanol, ether, and dilute acid. It is mainly used to prepare azo dyes, triphenylmethane dyes, vulcanization accelerators, saccharin, etc. It is also used as an analytical reagent.

Application:

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.
