CTAB was used in preparing buffer solutions prepared during the determination of organic acids in port wine capillary zone electrophoresis using indirect UV detection with 2,6-pyridinedicarboxylic acid.

General description

Hexadecyltrimethylammonium bromide (CTAB) is one of the most studied cationic surfactant.

Hexadecyltrimethylammonium bromide (CTAB) is a quaternary ammonium salt containing one long hydrophobic alkyl chain called amphiphile. The hydrophobic ions interact forming discrete aggregates possessing a hydrophobic core and a polar surface, called micelles in polar solution.
