Isopilocarpic acid Sodium salt is a tropane alkaloid derivative featuring a quaternary ammonium center, a bridged bicyclic skeleton, and a sodium-substituted carboxylate group. Its structure corresponds to the dehydrogenated analog of Pilocarpine, with a double bond between C-6 and C-7 positions, and a hydroxyl group at C-2. This compound arises as a degradation byproduct of Isopilocarpic, differing by a single oxidation state at the tropane ring. It serves as a critical HPLC reference standard for quantifying oxidative impurities in Isopilocarpic-containing pharmaceuticals.
