Overview of Cetyltrimethylammonium Bromide

Cetyltrimethylammonium Bromide, commonly known as CTAB, is a cationic surfactant used in laboratory, pharmaceutical, cosmetic, and industrial applications. It usually appears as a white to off-white crystalline powder.

The Cetyltrimethylammonium Bromide CAS No is 57-09-0, and the Cetyltrimethylammonium Bromide formula is C₁₉H₄₂BrN. Its structure contains a long hydrocarbon chain with a positively charged ammonium group, which gives it strong surface-active and antimicrobial properties.

Application of Cetyltrimethylammonium Bromide

1. Laboratory & Research Applications

Cetyltrimethylammonium bromide is widely used in laboratory research, especially in DNA extraction processes. In cetyltrimethylammonium bromide DNA extraction, CTAB helps remove proteins and other impurities, allowing clean DNA separation from plant and microbial samples.

It is often used with reagents such as Sodium Chloride and Tris Buffer in molecular biology protocols.

2. Pharmaceutical & Medical Applications

In pharmaceutical formulations, CTAB is used for its antimicrobial and surfactant properties. It helps control microbial growth and improves the stability of certain formulations.

It is sometimes used in antiseptic products and medical formulations where controlled antimicrobial action is required.

3. Cosmetic & Industrial Applications

In cosmetic and industrial products, Cetyltrimethylammonium Bromide works as a conditioning agent and emulsifier. It helps improve texture and stability in formulations.

It is also used in industrial cleaning products and chemical processing, often alongside Quaternary Ammonium Compounds and Cetrimonium Chloride.
