General description

4-tert-Butylbenzaldehyde is an important intermediate for the synthesis of medicines, dyes, flavor and fragrance compounds. It is reported to be formed during the partial oxidation of 4-tert-butyltoluene by hydrogen peroxide in glacial acetic acid, catalyzed by bromide ions in combination with cobalt(II) acetate or cerium(III) acetate.[1] Schiff base reaction between 4-tert-butylaniline and 4-tert-butylbenzaldehyde in ethanol has been carried out on-chip in the matrix assisted laser desorption ionization (MALDI) chamber, the formed imine was detected in real time.[2]

Application

4-tert-Butylbenzaldehyde is suitable for use in a kinetic study to evaluate the kinetic constants (KI) for inhibition of mushroom tyrosinase by 4-substituted benzaldehydes.[3]
