4,5-Dimethoxy-2-nitrobenzoic acid Chemical Properties,Usage,Production

Chemical Properties

Yellow crystalline powder

Uses

4,5-Dimethoxy-2-nitrobenzoic acid was used in the synthesis of 4,5-dimethoxy-2-nitrobenzamide and 6,7-dimethoxyquinazoline derivatives.

Application

4,5-dimethoxy-2-nitrobenzoic acid in the reaction with organotin oxides/halides yields the organotin carboxylates in anhydrous toluene. The resulting triorganotin carboxylates are one-dimensional polymers that are solid with trigonal bipyramidal geometry, while in solution, they are tetrahedral. Reaction of di-n-butyl tin oxide with 4,5-dimethoxy-2-nitrobenzoic acid yields Tetrabutylbis(4,5-dimethoxy-2-nitro benzoate)Distannoxane Dimer crystallizes as the usual dicarboxylatotetraorganodistannoxane dimer[1-2].

General Description

4,5-Dimethoxy-2-nitrobenzoic acid is a nitroaromatic compound.

Synthesis

In 3,4-dimethoxy-6-nitrobenzaldehyde (10 g)The reaction medium (20 mL of water, 30 mL of methanol)Acetic acid (3.5 mL), 30% hydrogen peroxide (9 mL)Stir well and add sodium chlorite (content 80%, 9g) in water (5mL); Stirring warming to about 50, monitoring the reaction, After the reaction was completed, sodium bisulfite (10.5 g) was added to quench the reaction, The solvent was evaporated to dryness, the product was dissolved in a solution of sodium hydroxide (6g × 10mL)Filtered to remove impurities, the filtrate was added sulfuric acid to pH 1 precipitated product, Filter and dry and obtained product 4,5-Dimethoxy-2-nitrobenzoic acid 10g (93% yield, high-performance liquid chromatography 99.5% purity).
