4-Hydroxy-3,5-dinitrobenzoic acid

Description:

4-Hydroxy-3,5-dinitrobenzoic acid, with the CAS number 1019-52-9, is an organic compound characterized by its aromatic structure featuring a benzoic acid core substituted with two nitro groups and a hydroxyl group. This compound typically appears as a yellow crystalline solid and is known for its strong acidic properties due to the carboxylic acid functional group. The presence of nitro groups contributes to its electron-withdrawing characteristics, which can influence its reactivity and stability. It is often used in organic synthesis and as an intermediate in the production of dyes and pharmaceuticals. Additionally, the hydroxyl group can participate in hydrogen bonding, affecting its solubility in various solvents. The compound is also of interest in studies related to environmental chemistry and toxicology, as nitro-substituted compounds can exhibit significant biological activity. Proper handling and safety precautions are essential due to its potential toxicity and environmental impact.

3,5-Dinitro-4-hydroxybenzoic acid

CAS: 1019-52-9

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.
