4-Nitrophenylacetic acid Usage And Synthesis
  • Chemical PropertiesBeige to yellow crystalline powder
  • UsesIntermediate for dyestuffs, pharmaceuticals, penicillin precursors, local anesthetics.
  • DefinitionChEBI: A monocarboxylic acid that is phenylacetic acid carrying a nitro substituent at position 4.
  • Safety ProfileModerately toxic intraperitoneal route. Mutation data reported. When heated to decomposition it emits toxic vapors of NOx.
  • Purification MethodsCrystallise 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.]
