Cetyltrimethylammonium bromide

It is one of the components of the topical antiseptic cetrimide. The cetrimonium (hexadecyltrimethylammonium) cation is an effective antiseptic agent against bacteria and fungi. Cetyltrimethylammonium bromide (CTAB) was from Amresco Inc. The mesoporous silica was synthesized by a two-phase route.

In a typical synthesis, the lower aqueous phase was a 15. HCl (molar ratio) and the upper oil phase was 0.

TEOS dissolved in 0. It has a role as a surfactant and a detergent. It is a quaternary ammonium salt and an organic bromide salt. It contains a cetyltrimethylammonium ion. Read full article at.

Edit article at. In view of understanding the nature of molecular interactions between surfactant and drug, here we report the experimental conductance (κ), densities (ρ) and ultrasonic velocities (u) of cationic surfactant cetyltrimethylammonium bromide, CTAB (-mM) in 2. M aqueous solution of antidiabetic drug metformin hydrochloride as a solvent at different temperatures (30 30 31K).

Flotation-Spectrophotometric Method for Separation and Determination of Trace Amounts of Copper. On the other han the CTAB ( cetyltrimethylammonium bromide ) method uses an absorbing agent with much larger molecules (as compared to nitrogen), which more effectively measures the actual surface area available to rubber.

We are unable to retrieve the vendor information for this entry at this time. Cetrimonium bromide is hexadecyltrimethylammonium. Cetrimide is a mixture of tetradecyltrimethylammonium (mostly), dodecyltrimethylammonium, and hexadecyltrimethylammonium. They dissociate in aqueous solution, forming a relatively large and complex cation, which is responsible for their surface activity, and a smaller inactive anion.

B (RB), crystal violet (CV), and methylene blue (MB) from aqueous environment. Ethyltrimethylammonium bromide. Ethanaminium, N,N,N-trimethyl, bromide.

Long-chain quaternary ammonium surfactants, such as cetyltrimethylammonium chloride (CTAC), are generally combined with long-chain fatty alcohols, such as stearyl alcohols, in formulations of hair conditioners and shampoos. M, Na (°C) 61Cationic surfactant used instead of SDS in electrophoresis of highly charged and membrane protein subunits (1). Surfactant for modifying silica for HPLC (2). Examples of effect: Damage metals.

The highly packed cetyltrimethylammonium bromide (CTAB) bilayer built up on the surface of gold nanorods (AuNRs) when synthesized by the seed-mediated procedure hampers the complete ligand exchange under experimental conditions that preserves the stability of the dispersions.

Slightly soluble in acetone. Insoluble in benzene and diethyl ether. Molecular weight : 364. They are coming from countries around the world.

Hexadecyl)trimethylammonium bromide is a cationic surfactant in hair conditioning products. It acts as a phase-transfer catalyst for the preparation of polyamide, polycarbonate and polythiocarbonate.

It facilitates ligand-free palladium salt-catalyzed Heck and Suzuki cross-coupling reactions in water. A wide variety of cetyltrimethylammonium bromide options are available to you, There are suppliers who sells cetyltrimethylammonium bromide on Alibaba.

The top countries of suppliers are India, China, from which the percentage of cetyltrimethylammonium bromide supply is 2%, 97% respectively.
