| 5-Nitrosalicylic acid Usage And Synthesis |
| Chemical Properties | yellow powder | | Uses | 5-Nitrosalicylic Acid is a salicylic acid derivative with anti-inflammatory effect against colitis. | | Definition | ChEBI: A monohydroxybenzoic acid in which the hydroxy group is ortho- to the carboxylic acid group and which has a nitro substituent para- to the phenolic hydroxy group. | | Synthesis Reference(s) | Tetrahedron Letters, 36, p. 2377, 1995 DOI: 10.1016/0040-4039(95)00281-G | | General Description | 2-Hydroxy-5-nitrobenzoic acid inhibits the activity of wild type-bovine low Mr protein tyrosine phosphatase. The inhibition constant has been evaluated. | | Flammability and Explosibility | Nonflammable | | Purification Methods | Crystallise the acid from Me2CO (charcoal), then twice more from Me2CO alone, aqueous EtOH (m 234-236o) or H2O (m 232-233o).
