Diallyldimethylammonium chloride
Manufactured by Merck Group
Sourced in Germany
Diallyldimethylammonium chloride is a chemical compound that is commonly used as a coagulant and flocculant in water treatment applications. It is a cationic polymer that can effectively remove suspended particles, colloids, and dissolved organic matter from water. The key function of this product is to facilitate the aggregation and sedimentation of these impurities, thereby improving the clarity and quality of the treated water.

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.
