General description

Tetrabutyammonium bisulfate (TBAHS) is an ion-pairing reagent. It acts as a catalyst in hydrolysis of aziridines and epoxides and the catalyst can be recycled.

Application

TBAHS was suitable as ion-pairing reagent in determination and separation of thallium using ionic liquid-assisted ion-pairing liquid-liquid microextraction and inductively coupled plasma mass spectrometry. It was suitable as mobile phase component for a HPLC-UV analysis to quantify chondroitin sulfate.

Cloruro de tetrabutilamonio

Sensitive determination of thallium species in drinking and natural water by ionic liquid-assisted ion-pairing liquid-liquid microextraction and inductively coupled plasma mass spectrometry.

Leticia B Escudero et al.

Journal of hazardous materials, 244-245, 380-386 (2012-12-29)

A fast and simple method involving separation and determination of thallium (Tl) species, based on novel ionic liquid-assisted ion pairing dispersive liquid-liquid microextraction (DLLME) method, was developed. Initially, Tl(III) was selectively complexed with chloride ion to form [TlCl(4)](-) chlorocomplex. Subsequently

Determination of chondroitin sulfate content in raw materials and dietary supplements by high-performance liquid chromatography with ultraviolet detection after enzymatic hydrolysis: single-laboratory validation.

David Ji et al.

Journal of AOAC International, 90(3), 659-669 (2007-06-22)

A method to quantify chondroitin sulfate in raw materials and dietary supplements at a range of about 5 to 100% (w/w) chondroitin sulfate has been developed and validated. The chondroitin sulfate is first selectively hydrolyzed by chondroitinase ACII enzyme to

Tetrabutylammonium bisulfate: a new effective catalyst for the hydrolysis of aziridines or epoxides.

Ren-Hua Fan et al.

Organic & biomolecular chemistry, 1(9), 1565-1567 (2003-08-21)

Bu4NHSO4 (TBAHS) is an effective catalyst for the hydrolysis of aziridines and epoxides under mild and non-metal conditions to give the corresponding beta-amino alcohols and 1,2-diols in high yields. The catalyst can be recycled.

The role of sodium in the salty taste of permeate.

K M Frankowski et al.

Journal of dairy science, 97(9), 5356-5370 (2014-07-16)

Many food companies are trying to limit the amount of sodium in their products. Permeate, the liquid remaining after whey or milk is ultrafiltered, has been suggested as a salt substitute. The objective of this study was to determine the

Photoinduced ligand exchange and DNA binding of cis-[Ru(phpy)(phen)(CH3CN)2]+ with long wavelength visible light.

R Bryan Sears et al.

Journal of inorganic biochemistry, 121, 77-87 (2013-01-29)

The complex cis-[Ru(phpy)(phen)(CH3CN)2](+) (phpy=2-phenylpyridine, phen=1,10-phenanthroline) was investigated as a potential photodynamic therapy (PDT) agent. This complex presents desirable photochemical characteristics including a low energy absorption tail extending into the PDT window (600-850nm) and photoinduced exchange of the CH3CN ligands, generating

Analysis of Difficult Polar Compounds using Sigma-Aldrich Ion Pair Reagents and Supelco Ascentis HPLC Columns

Because reversed-phase HPLC is primarily dependent on hydrophobic interactions between the stationary phase and analyte, ion pairing is occasionally necessary to obtain sufficient retention of polar, ionizable compounds.
