Quaternary Ammonium Cations and Salts
In this section, you will find a wide variety of building blocks that are formed from amines and are readily soluble in water. Quaternary ammonium cations and salts are characterized by a nitrogen atom bonded to four organic groups, creating a positively charged ion. These compounds are widely used in applications such as disinfectants, surfactants, and phase transfer catalysts. Their excellent water solubility and antimicrobial properties make them valuable in both industrial and research settings. At CymitQuimica, we provide a diverse selection of high-quality quaternary ammonium cations and salts to meet your needs.

CAS:(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. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.

CAS:Tetramethylammonium hydroxide is used to produce tetramethyl-ammonium azide. It is used as an anisotropic etchant of silicon, basic solvent in the development of acidic photoresist in photolithography process, as surfactant in the synthesis of ferrofluid and as a polarographic reagent. It finds application in the production of organic silicon, where it is used for computer silicon wafer surface brightener and cleaning agent. It is also involved in the purification of some metallic elements. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.
