O-toluidine wani sinadari ne na halitta wanda ke da amfani iri-iri. Ga manyan abubuwan da ake amfani da shi:

Masana'antar rini‌: ana amfani da ita wajen shirya rini na azo, rini na triphenylmethane, da sauransu, kuma a matsayin tsaka-tsakin rini, tana taka muhimmiyar rawa wajen kera rini daban-daban kamar GBC mai tushen ja da G mai tushen ja.
Masana'antar harhada magunguna: ana amfani da su wajen shirya magunguna kamar o-cloxacillin, methaqualone, bisoprolol da rhodin.
Masana'antar magungunan kashe kwari: ana amfani da su wajen haɗa magungunan kashe kwari kamar chlordimeform.
Sauran amfani: ana kuma amfani da shi azaman mai ƙara ƙarfin roba, maganin busar da fenti, da kuma saccharin na roba, da sauransu.
A taƙaice, ana amfani da o-toluidine sosai a rini, magunguna, magungunan kashe kwari da sauran fannoni na sinadarai, kuma muhimmin abu ne na haɗakar halitta.

Hanyoyin shirya o-toluidine sun haɗa da waɗannan:

Hanyar rage sinadarin hydrogenation: ana ƙara o-nitrotoluene da hydrogen zuwa cikin reactor, sannan ana yin aikin rage sinadarin a wani zafin jiki da matsin lamba don samar da o-toluidine.
Hanyar rage foda na ƙarfe‌: Ana rage o-nitrotoluene da foda na ƙarfe a cikin wani matsakaici mai narkewar acid, sannan a raba ɗanyen o-toluidine, sannan a sami tsantsar samfurin ta hanyar narkewar acid, ruwan alkali da sauran matakai‌.
Hanyar haɗa kai tsaye: ana yin o-nitrotoluene kai tsaye tare da ammonia a ƙarƙashin aikin mai kara kuzari don samar da o-toluidine, amma tsarkin samfurin yana da ƙasa.
Waɗannan hanyoyin suna da nasu halaye kuma sun dace da buƙatun samarwa daban-daban. A aikace-aikace, ana iya zaɓar hanyar shiri mai dacewa bisa ga takamaiman yanayin.
