1-Naphthalenesulfonic acid Chemical Properties,Uses,Production

Chemical Properties

grey fine crystalline powder

Uses

1-Naphthalenesulfonic acid was used as template molecule to prepare new non-covalent molecularly imprinted polymer for solid-phase extraction of naphthalene sulfonates.

Definition

ChEBI: Naphthalene-1-sulfonic acid is a naphthalenesulfonic acid.

General Description

Mechanism of metabolism of 1-naphthalenesulfonic acid by green algae Scenedesmus obliquus has been investigated.

Purification Methods

Crystallise 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.]
