Sodium 2-naphthalenesulfonate Chemical Properties,Usage,Production

Chemical Properties

white to pale grey powder

Uses

Sodium 2-naphthalenesulfonate may be used as an analytical reagent for iodine speciation analysis in urine using ion-pair reversed phase liquid chromatography coupled to inductively coupled plasma mass spectrometry (RP-LC-ICP-MS).

General Description

Sodium 2-naphthalenesulfonate induces various aggregates such as spherical and elongated micelles, tubular and rodlike aggregates, as well as vesicles, when added in to the aqueous solution of a gemini surfactant C12C2C12(Me) (1,2-ethanediyl-bis-(dodecyldimethylammonium bromide)). It has been studied as a solute to evaluate the performance of resin particles.

Purification Methods

It crystallises from hot 10% aqueous NaOH or water and is dried in a steam oven. [Beilstein 11 IV 521.]
