1-Naphthalenesulfonic acid Usage And Synthesis
Chemical Propertiesgrey fine crystalline powder
Uses1-Naphthalenesulfonic acid was used as template molecule to prepare new non-covalent molecularly imprinted polymer for solid-phase extraction of naphthalene sulfonates.
DefinitionChEBI: Naphthalene-1-sulfonic acid is a naphthalenesulfonic acid.
General DescriptionMechanism of metabolism of 1-naphthalenesulfonic acid by green algae Scenedesmus obliquus has been investigated.
Purification MethodsCrystallise the acid from conc HCl and twice from H2O. The S-benzylisothiuronium salt has m 137o (from aqueous EtOH). [Beilstein 11 H 155, 11 III 383, 11 IV 521.]
