General description
Sodium pentanesulfonate is an anionic surfactant, which is used in the analysis of small organic molecular compounds, pharmaceutical products, and metabolites using reversed-phase high-performance liquid (RP-HPLC) and micellar electrokinetic chromatography. Sonochemical and sonoluminescent studies by electron paramagnetic resonance spectroscopy (EPR) and spin-trapping techniques have been reported on various ion-pairing reagents, like sodium pentanesulfonate.
Application
Ion-associating reagent for HPLC, including analyses of peptides and proteins.

A simple and selective micellar electrokinetic chromatography (MEKC) with UV detection is described for simultaneous determination of amikacin, tobramycin, and kanamycin A, performed in Tris buffer (180 mM; pH 9.1) with 300 mM sodium pentanesulfonate (SPS) as an anionic surfactant.

Sonolysis of argon-saturated aqueous solutions of the nonvolatile surfactants sodium dodecyl sulfate (SDS) and sodium 1-pentanesulfonate (SPSo) was investigated at three ultrasonic frequencies under both continuous wave (CW) and pulsed ultrasound. Secondary carbon-centered radicals were detected by spin trapping using
