Description

General description

Cetrimonium bromide(CTAB) is a quaternary ammonium derivative known to enhance anti-tumor activity. It is one of the components of the broad-spectrum antiseptic cetrimide and may also be used as a buffer for DNA extraction.

Application

CTAB may be used as a reference standard for the determination of:
• CTAB in various water samples by combining a dispersive liquid-liquid microextraction (DLLME) technique with high performance liquid chromatography.
• CTAB in pharmaceutical formulations by reversed-phase high-performance liquid chromatography (RP- HPLC).

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
