General description

Vibrational spectral investigations of ethyl 4-aminobenzoate in solid phase have been reported. It affords an electroactive conducting copolymer with o-anisidine, via an electrochemical synthesis employing cyclic voltammetry.

Application

Ethyl 4-aminobenzoate may be used in the synthesis of ethyl 4-[(E)-(2-hydroxy-4-methoxyphenyl)methyleneamino] benzoate (Schiff base), via reaction with 2-hydroxy-4-methoxybenzaldehyde.
