Product Details

Dodecyl Trimethy Lammonium Bromide CAS#1119-94-4

Dodecyltrimethylammonium bromide is a white to off-white crystalline powder or crystal. The pure substance is a colorless crystal and is prone to absorbing moisture when exposed to air. It is highly soluble in water, forming a transparent solution. The aqueous solution is weakly alkaline (pH approximately 8 to 9, due to the hydrolysis of quaternary ammonium salts).

Product Usage

(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.
