o-Toluidine (ortho-toluidine) is an organic compound with the chemical formula CH 3 C 6 H 4 NH 2. It is the most important of the three isomeric toluidines . It is a colorless liquid although commercial samples are often yellowish.
The other toluidine isomers are used in the production of dyes. They are a component of accelerators for cyanoacrylate glues. In some patients o-toluidine is a metabolite of prilocaine, which may cause methemoglobinemia. This is then treated with methylene blue.
2-Tolidine (orthotolidine, o-tolidine; not to be confused with o-toluidine) is an organic compound with the chemical formula (C 6 H 4 (CH 3)NH 2) 2. Several isomers are known; the 3-tolidine derivative is also important commercially. It is a colorless compound although commercial samples are often colored. It is slightly soluble in water.
Preparations of this chemical may be named as a hydrochloride (e.g. "3-chloro-p-toluidine hydrochloride", CPTH), indicating that hydrochloric acid has been used to neutralize the molecule to a salt in which the amine group is protonated and a chloride counterion is present; otherwise the free base is indicated.
Color Developing Agent 2 is the second in the series of color developing agents used in developing color films.It is commonly known as CD-2 and is chemically known as 4-diethylamino-o-toluidine, 1,4-benzenediamine, N4,N4-diethyl-2-methyl-, N1,N1-diethyl-3-methylbenzene-1,4-diamine, or 4-(diethylamino)-2-methylaniline.

Mauveine A (C 26 H 23 N + 4 X −) incorporates 2 molecules of aniline, one of p-toluidine, and one of o-toluidine. Mauveine B (C 27 H 25 N + 4 X −) incorporates one molecule each of aniline, p-toluidine, and two of o-toluidine. In 1879, Perkin showed mauveine B related to safranines by oxidative/reductive loss of the p-tolyl group. [7]
