I'm looking for a stable method to assay for benzethonium chloride (in products) by HPLC. Does anyone have an established method that they can share?
This might help: Biologicals. 2006 Feb 18; [Epub ahead of print] Determination of benzethonium chloride in Anthrax Vaccine Adsorbed by HPLC. Wang H, Del Grosso AV, May JC.
