3,5-Dinitro-2-methylbenzoic acid Chemical Properties,Usage,Production

Chemical Properties

light yellow fine crystalline powder

Uses

2-Methyl-3,5-dinitrobenzoic acid was used to synthesis heterocyclic derivatives and in the synthesis of isoquinolone.

General Description

Synthesis of a series of heterocyclic derivatives of 3,5-dinitro-o-toluic acid has been reported.

Purification Methods

Crystallise the acid from H2O or aqueous EtOH. The ammonium salt forms yellow crystals from EtOH with m 218-219o, and the urea salt has m 189-190o (prisms from EtOH). [Beilstein 9 H 474, 9 II 323, 9 III 2316.]
