General description

Benzyldimethylhexadecylammonium chloride is a cationic surfactant.

Application

Benzyldimethylhexadecylammonium chloride has been used in a study to assess the removal of cationic surfactants from aqueous solutions using activated carbon cloth (ACC). It has also been used in a study to investigate the prototropic behavior of the dye, 7-hydroxy-4-methylcoumarin (7H4MC).

The adsorption of the cationic surfactant benzyldimethylhexadecylammonium (BDMHA(+)) chloride has been studied at the hydrophilic silica-water interface by Raman spectroscopy in total internal reflection geometry (TIR Raman). This Raman spectroscopic technique takes advantage of an evanescent electric field that is

The prototropic behavior of the dye, 7-hydroxy-4-methylcoumarin (7H4MC), has been studied in cationic benzyldimethylhexadecylammonium chloride (BDHC) and nonionic poly(oxyethylene)(tetramethylbutyl)phenyl ether (TritonX-100, TX-100) reverse micelles using ground-state absorption and steady-state and time-resolved fluorescence measurements. The results have been compared with the

Integral membrane proteins, particularly those with more than one transmembrane domain, have traditionally been difficult to separate by two-dimensional electrophoretic methods. Here we report the adaptation of a previously published procedure [D. E. Macfarlane (1989) Anal. Biochem. 176, 457-463] for
