Documented Uses

• Intermediate used in the organic synthesis of dyes, reagents, and other chemicals; [ACGIH]
• Smoking cigarettes [Category: Food & Drugs]
• p-Toluidine is used exclusively as an intermediate in chemical processes. The largest subsequent product of p-toluidine is 4B acid (4-toluidine-3-sulfonic acid, an intermediate for pigment production) which amounts to about 2/3 of world p-toluidine demand. p-Toluidine is also used in minor amounts for the manufacturing of : m-nitro-p-toluidine, acetoacetate-p-toluidine, di-p-toluidinoterephthalic acid, which all are intermediates in the production of pigments; dehydro-p-toluidine, an intermediate in the production
• Manufacture of various dyes and other organic chemicals. Reagent for lignin, nitrite, chloroglucinol
• Dyes: Basic Red 9, Acid Green 25
• Preparation of ion exchange resins
