Pretreatment for water use: Biopharmaceutical companies also use purified water as pretreatment in systems while in the preparing of WFI and pure steam production.
At the moment, Water For Injection doesn't have to be used during the finishing methods of synthesis/purification of drug substances for parenteral use.
