Orthonitrobenzoic

Orthonitrobenzoic acid is an organic compound with the chemical formula C6H4(NO2)2(OH). It is a derivative of benzoic acid, where two hydrogen atoms have been replaced by nitro groups, and one hydrogen atom has been replaced by a hydroxyl group. This compound is a white crystalline solid that is soluble in water and organic solvents.

Orthonitrobenzoic acid is primarily used as a reagent in organic synthesis. It can undergo various reactions, such as nucleophilic substitution and condensation, to form a wide range of compounds. It is also used in the synthesis of dyes, pharmaceuticals, and other organic compounds.

The compound is typically prepared by the nitration of orthohydroxybenzoic acid. The nitration process involves the reaction of orthohydroxybenzoic acid with a nitrating agent, such as a mixture of concentrated nitric and sulfuric acids, to introduce the nitro groups.

Orthonitrobenzoic acid is a potentially hazardous substance. It can cause skin and eye irritation, and inhalation of its dust can cause respiratory irritation. It is also a potential carcinogen, and prolonged exposure should be avoided. Proper personal protective equipment, such as gloves, safety glasses, and a lab coat, should be worn when handling this compound.
