Description

3,5-Dinitro-4-hydroxybenzoic acid (DNHB) is an organic compound that is used as a reagent in organic synthesis. DNHB has been shown to be a nucleophile, reacting with chloride ions from HCl and forming the corresponding 3,5-dinitrosalicylic acid (DNSA) salt. This reaction has been shown to be efficient at low temperature and pH values. The efficiency of this reaction has been shown to increase by the addition of halides such as fluoride and bromide. Electrospray ionisation mass spectroscopy analysis of DNHB has also revealed that it is an anion with a molecular weight of 228.3 g/mol. DNHB is synthesised by reacting benzoic acid with nitrous acid and hydrochloric acid, followed by treatment with concentrated sulfuric acid.
