532-02-5 Usage

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.]

Check Digit Verification of cas no

The CAS Registry Mumber 532-02-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,3 and 2 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 532-02:
(5*5)+(4*3)+(3*2)+(2*0)+(1*2)=45
45 % 10 = 5
So 532-02-5 is a valid CAS Registry Number.

Micellar Head-Group Size and Anion Nucleophilicity in SN2 Reactions

Bonan, Cristiana,Germani, Raimondo,Ponti, Pier Paolo,Savelli, Gianfranco,Cerichelli, Giorgio,et al.

, p. 5331 - 5336 (1990)

Rates of reaction of OH- with methyl naphthalene-2-sulfonate (MeONs) in aqueous cationic surfactants (C16H33NR3OH, R = Me, Et, n-Pr, n-Bu, and cetylquinuclidinium hydroxide) increase with increasing surfactant and hydroxide ion concentrations.The variations of rate constants can be fitted to an equation that describes the distribution of both reactants between water and micelles in terms of Langmuir isotherms.The Langmuir coefficients for OH- decrease in the head-group sequence Me3N > quinuclidinium > Et3N > Pr3N > Bu3N.The second-order rate constants at the micellar surfaces are not very sensitive to the bulk of the head group, although they increase at high added OH-.Rate constants for attack of water on micellar-bound substrate increase with increasing bulk of the head group.
