4-Nitrophenylacetic acid is a member of the class of phenylacetic acids that is phenylacetic acid in which the phenyl grup is substituted at the para- position by a nitro group. | | Uses | (4-Nitrophenyl)acetic Acid used in the synthesis of 5,7-dimethyl-2-aryl-3H-pyrrolizin-3-ones which may act as angiogenesis inhibitors. Also used in the one step construction of amino-substituted squaraine dye. | | Uses | Intermediate for dyestuffs, pharmaceuticals,
penicillin precursors, local anesthetics. | | Definition | ChEBI: A monocarboxylic acid that is phenylacetic acid carrying a nitro substituent at position 4. | | Safety Profile | Moderately toxic intraperitoneal route. Mutation data reported. When heated to decomposition it emits toxic vapors of NOx. | | Purification Methods | Crystallise the acid from EtOH/water (1:1), then from sodium-dried diethyl ether and dry it over P2O5 in vacuo. The styphnate has m 196.5-197o (prisms from EtOH). The amide has m 191o (from EtOH). [Beilstein 9 III 2284, 9 IV 1698.] |
