Answers:
HydrochlorideFrom our old friend the Wikipedia:Converting otherwise insoluble amines into their hydrochlorides is a common way to make them water and acid-soluble. This is particularly desirable for substances used in medications. Many pharmaceutical substances used are prepared as hydrochlorides so that they may be quickly absorbed in the gastrointestinal tract.
