Regal® Algaecide 50 (50% Quaternary Ammonium) Reviews

“This is 50% alkyldimethylbenzylammonium chloride (the other 50% is 40% water with 10% isopropyl alcohol) - which can be broken down into the aforementioned Amomonium cation for synthesis of quaternary ammonium-imide salt electrolytes in custom electric double layer capacitors. Not sure how this stuff works as an algaecide or if $20 is a good price for algaecide - but its the only product I found that contained a large percentage of a quaternary ammonium cation that could be easily separated from the rest of the molecule (after separation from the solution of course).”
