5-Chloro-2-nitrobenzoic acid Usage And Synthesis

Chemical Properties

light yellow to yellowish-green crystalline powder.
5-Chloro-2-nitrobenzoic acid is a crystalline solid sparingly soluble in cold water but readily soluble in hot water and also in ethanol and benzene. Its electrolytic dissociation constant is 1.52 × 10?2 (25 °C), and its melting point is 139 °C.

Uses

5-Chloro-2-nitrobenzoic acid was used as a component of 5,5′-dithiobis-2-nitrobenzoic acid, which found application to the determination of the acid-soluble disulphide content of the blood. Benzene and some of its derivatives (e.g. chloronitrobenzoic acids) have been shown to cause alterations in heme and globin synthesis. Chloronitrobenzoic acids inhibited the activity of δ-aminolevulinic acid (δ-ALA) and enhanced ferrochelatase (FC) activity. 5-Chloro-2-nitrobenzoic acid was also used as component of synthesis of 2-aryl 4(3H)-quinazolinones and 6-pyrrolidinyl-2-(2-substituted phenyl)-4-quinazolinones, which are potential anticancer candidates[1].
