  • DefinitionChEBI: A member of the class of benzaldehydes that is vanillin in which the hydrogen ortho- to the hydroxy group is substituted by a nitro group.
  • Purification MethodsIt forms yellow plates from AcOH and needles from EtOH [Slotta & Szyszke Chem Ber 68 184 1935]. With diazomethane, 5-nitro-3,4-dimethoxyacetophenone is formed [Brady & Manjunath J Chem Soc 125 1067 1924]. The methyl ether crystallises from EtOAc or AcOH, m 88o, 90-91o, and the phenylhydrazone has m 108-110o (from aqueous EtOH). [Finger & Schott J Prakt Chem [2] 115 288 1927.] The oxime has m 216o (from EtOH or AcOH), and the oxime acetate has m 147o (from aqueous EtOH) [Vogel Monatsh Chem 20 384 1899, Brady & Dunn J Chem Soc 107 1861 1915].
