Description and Uses

(1-Dodecyl)trimethylammonium bromide is used as a surfactant, as an emulsifier of rubber and asphalt and as an anti-static agent of synthetic fiber. It acts as an ionic surfactant and useful in the preparation of gold nanopartilces along with sodium dodecylsulfate. It is also used as paint strippers and foaming stabilizers. It is used to prepare dodecyltrimethylammonium bromide. By using conductimetry, density measurements, and small angle neutron scattering, it is used to study the micelle formation in water-dimethylsulfoxide mixture. Further, it is a useful biochemical for proteomics research.
