Insofar as an alternative

Insofar as an alternative formulation of Ibuprofen is as a lysine salt, I would recommend raising the pH with Ammonium Hydroxide to create the ammonium salt of the ibuprofen (an acid in it's natural state).  The ammonium counter ion shouldn't interfere with subsequent analyses; especially if you don’t take the pH any higher than needed to solublize the ibuprofen.
