Ibuprofen was converted into its derivatives: ibuprofen-ester, ibuprofen-hydrazide, ibuprofen imine-benzaldehyde and ibuprofen imine-salicylaldehyde in three stages: esterification using microwave radiation, formation of hydrazide, and Schiff's base reaction. Ibuprofen (1-) is a monocarboxylic acid anion that is the conjugate base of ibuprofen, obtained by deprotonation of the carboxy group; major species at pH 7.3. It is a conjugate base of an ibuprofen.
