Tetradecyltrimethylammonium bromide Usage And Synthesis

Physical properties

Cetrimide is a white fine powder crystal with a melting point of 245°C to 250°C. A rough estimate of its density is 1.1328. It is soluble in water with a solubility of 20 g/100 mL.

Description

MiTMAB (1119-97-7) is a dynamin I/II inhibitor targeting the dynamin-phospholipid interaction and inhibiting dynamin GTPase activity with a Ki=940nM.1 Rapidly and reversibly inhibits multiple forms of endocytosis with no acute cellular damage1. A useful pharmacological tool for studying dynamin-mediated trafficking events.2 Induces cytokinesis failure and apoptosis in human cancer cells.3 Induces cytoprotective autophagy in human Jurkat T cells.4

Uses

Disinfectant; deodorant; laboratory reagent.

Uses

Myristyltrimethylammonium has been used in a study to assess a surfactant-controlled synthetic method to obtain a nanophase of mesoporous ceria-zirconia solid solution containing cationic defects in the crystalline structure.??It has also been used in a study to determine the low molecular weight of organic acids in soils and plants by capillary zone electrophoresis.

Definition

Myristyltrimethylammonium bromide is an organic molecular entity.

General Description

Myristyltrimethylammonium bromide is a cationic/zwitterionic type of surfactant.

Purification Methods

Crystallise the bromide from acetone or a mixture of Me2CO and >5% MeOH or Me2CO/EtOH. Wash it with diethyl ether and dry it in a vacuum oven at 60o. It is a cationic detergent. Its solubility is 1g/5g H2O. [Dearden & Wooley J Phys Chem 91 2404 1987, Shelton et al. J Am Chem Soc 68 754 1946, Beilstein 4 III 419, 4 IV 813.]
