4-Phenoxybenzaldehyde is a phenolic compound that has potent inhibitory activity against bacteria. It was shown to have the highest antibacterial activity among alkanoic acids, with an MIC of less than 2 µg/mL. 4-Phenoxybenzaldehyde is produced by the condensation of phenol and acetaldehyde in the presence of a solid catalyst and potassium hydroxide. This reaction produces a mixture of products, including 4-phenoxybenzaldehyde, which can be purified by recrystallization or column chromatography. The biosynthetic pathway for 4-phenoxybenzaldehyde in plants has been elucidated and includes two steps: one involving pyrazole ring formation and another involving hydroxyl group formation.

Applications 4-Phenoxybenzaldehyde is a precursor for para-Cypermethrin (C989400). It can cause acute toxicity to the protozoan ciliate Tetrahymena pyriformis, which is predicted by quantitative structure-active relationship (QSAR) models. References Roy, Kunal., et al.: J. Hazard.
