light yellow crystals | [Uses]
3-Nitrobenzoic acid was used to investigated the role of ozone as additional decomposition or finishing reagent in the degradation of o-, m- and p-nitobenzoic acids | [Application]
3-Nitrobenzoic acid is an intermediate of photosensitive materials, functional pigments and drugs. In the pharmaceutical industry, it is used to produce bile acid, acetic acid and so on.
m-nitrobenzoic acid is a reagent used in the coupling of allyl acetate to allylic, aliphatic and benzylic alcohols. It is also used as a chemoattractant against Pseudomonas strains. | [Preparation]
3-Nitrobenzoic acid is prepared by nitrating benzoic acid at low temperature. Approximately 20% of the 2-nitro isomer and 1.5% of the 4-nitro isomer are co-produced. The 3-nitrobenzoic acid can be purified by recrystallization of the sodium salt. The oxidation of 3-nitrobenzaldehyde, prepared by the controlled oxidation of benzaldehyde, gives a higher yield. | [Synthesis Reference(s)]
