The Uses of 4-Isopropylbenzoic acid

4-Isopropylbenzoic acid (cuminic acid) was used in the synthesis of three new triorganotin carboxylates bearing methyl, butyl and phenyl substituents at tin, respectively. The products were fully characterized by spectroscopic and thermal techniques, with regard to the coordination number of tin atom, in solution and in the solid state.

What are the applications of Application

4-Isopropylbenzoic acid is used in the synthesis of triorganotin carboxylates

Definition

ChEBI: A cumic acid that consists of benzoic acid substituted by an isopropyl group at position 4.

Production Methods

4-Isopropylbenzoic acid is produced 1) by oxidation of Cuminic aldehyde (evt. in the presence of water). 2) by oxidation of para-Cymene under alkaline or acid conditions.
