Tetradodecylammonium bromide

Manufactured by Merck Group
Sourced in Germany

Tetradodecylammonium bromide is a quaternary ammonium salt that is commonly used as a surfactant and phase transfer catalyst in laboratory applications. It is a white, waxy solid with a high melting point. The compound acts as a cationic surfactant and can be used to facilitate the transfer of ionic species between immiscible phases.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
