A fluorinated anisidine building block

A synthetic substrate in organic synthesis and a precursor for bicyclic heterocycles


4-Methoxy-3-(trifluoromethyl)aniline (CAS number 393-15-7) is a derivative of anisidine, with a trifluoromethyl substituent introduced at 3-position. 4-Methoxy-3-(trifluoromethyl)aniline is also referred to as anisole, due to the presence of a methoxybenzene moiety. 4-Methoxy-3-(trifluoromethyl)aniline is commonly utilised as a substrate in organic synthesis for studying amine/aniline-related reactions.

4-Methoxy-3-(trifluoromethyl)aniline is also used for synthesising substituted bicyclic heterocycles, including quinolines, benzotriazoles and benzimidazoles analogues. These applications are particularly relevant to the development of active pharmaceutical ingredients (APIs), showing strong antitumor and antiviral activities.
