What is 2,4-DINITROBENZOIC ACID?
Chemical properties
pale yellow crystalline powder
The Uses of 2,4-DINITROBENZOIC ACID
2,4-Dinitrobenzoic acid was used in the spectrophotometric determination of diazepam in pure samples and in its pharmaceutical preparations. It was employed as chromophore probe for analysis of perfluorinated carboxylic acids in water by capillary zone electrophoresis. It can be used to produce 2,4-dinitro-benzoyl chloride.
The Uses of 2,4-DINITROBENZOIC ACID
2,4-Dinitrobenzoic acid can be used as a reactant:
- In decarboxylative C-N cross-coupling reactions.
- To synthesize Zwitterionic azaspirocyclic hydantoins by reacting with various carbodiimides via in situ intramolecular dearomatization reaction.
- To prepare 1-(2,4-dinitrophenyl)ethanone by condensation with dimethyl malonate and subsequent decarboxylation reaction.
It can also be used in the spectrophotometric determination of diazepam in pure samples and in its pharmaceutical preparations. In capillary zone electrophoresis, it can be employed as chromophore probe for the analysis of perfluorinated carboxylic acids in water.
