2,5-Dimethylbenzoic acid Usage And Synthesis

Chemical Properties

white to off-white crystalline powder

Uses

2,5-Dimethylbenzoic acid was used in the synthesis of new derivatives of [2₄]paracyclophane. It was used as starting reagent in the synthesis of methyl 2,5-dimethylbenzoate.

Definition

ChEBI: A dimethylbenzoic acid in which the two methyl groups are located at positions 2 and 5.

General Description

2,5-Dimethylbenzoic acid is a metabolite of pseudocumene (1,2,4-trimethylbenzene).

Purification Methods

Steam distil the acid, then crystallise it from EtOH or H2O (m 134-134.5o). [Beilstein 9 H 534, 9 IV 1802.]
