Sodium 1-octanesulfonate monohydrate (NaOS) is an ion-pairing reagent.[1]

Anwendung

NaOS has been used as ion-pairing reagent for ultra-high performance liquid chromatography (UPLC) analysis with photodiode array detection to estimate paraquat (methyl viologen) in tissue homogenate.[1] It may also be used in determination of dopamine and its metabolites in brain microdialysates using liquid chromatography combined with electrospray ionization tandem mass spectrometry (LC–ESI-MS/MS).[2]

A sensitive assay method was developed for a parallel, rapid and precise determination of dopamine and its metabolites, homovanillic acid, 3-methoxytyramine and 3,4-dihydroxyphenylacetic acid, from brain microdialysates. The method consisted of a pre-treatment step, freeze-drying (lyophilization), to concentrate dopamine and

We have observed dual transitions in various physical properties while investigating the surfactant-like behavior of the ionic liquid (IL) 1-butyl-3-methylimidazolium octylsulfate [C(4)mim][C(8)SO(4)] in aqueous media. Interestingly, in conductivity measurements, it was found that the second transition, which is comparatively weak

Following a detailed study, a rapid and sensitive assay for the naturally fluorescent collagen cross-links pyridinoline and deoxypyridinoline has been developed using ion-pair reversed-phase high-performance liquid chromatography in the presence of 1-octanesulphonic acid (OSA). Pyridinoline and deoxypyridinoline were separated on
