Is there a reason why scopolamine is listed as a quaternary ammonium compound in this template? The structure of scopolamine has a quartenary ammonium group no more than atropine and hyoscyamine, that are listed as tertiary amines, have. Some derivatives of scopolamine such as butylscopolamine and methylscopolamine are of course quaternary ammonium compounds. --MiPe (talk) 18:12, 14 November 2012 (UTC)[reply]
