3-chloro-4-methylaniline

3-Chloro-4-methylaniline (CAS 95-74-9), also known as 2-Chloro-4-aminotoluene and abbreviated as 3-CPT, is an aromatic amine intermediate used primarily in the synthesis of agrochemical active ingredients.

Where is 3-chloro-4-methylaniline used?

• Agrochemicals: key building block in the manufacture of herbicides and other crop protection compounds
• Herbicide production: most commonly consumed in the production of herbicide active substances
• Its chloro-substituted aniline structure is incorporated into the final molecule during multi-step synthesis.
• Urea-based and amide-based herbicides targeting broadleaf and grassy weeds
• Dye and pigment chemistry: precursor, though agrochemical synthesis represents the dominant commercial demand

Good to know: Handling should be conducted in accordance with safety data sheets due to the characteristic toxicity profile of aromatic amines.

Commercial specifications

• Purity typically specified at 98% or higher by GC
• Drum and IBC packaging are conventional for industrial quantities
• Smaller quantities are available for R&D procurement
