In this work we report efficient molecularly imprinted polymer (MIP) based carbon paste electrode sensor for the determination of diphenylamine in aged propellant. Initially, diphenylamine (DPA)‐MIP was synthesized by using methacrylic acid (monomer) and ethylene glycol dimethyacrylate (cross‐linker). Developed DPA‐MIP was analyzed by Fourier transform infrared spectroscopy and Field‐emission scanning electron microscopy. The sensor was incorporated as electrode in cyclic voltammetry. The sensor response was linear in the range of 0.5–3 mM DPA concentration. The lower detection limit obtained for sensor was 0.1 mM. The developed sensor was used for the determination of DPA in propellant systems. Same electrode was used for three repeated analysis without significant decrease in efficiency.
