Pilocarpic acid Sodium salt

Pilocarpic acid Sodium salt is a tropane alkaloid derivative featuring a bicyclic tropane skeleton with a nitrogen bridge connecting two cyclohexane rings. Its structure incorporates a substituted pyrrolidine ring and a carboxylate group deprotonated by sodium ion coordination. This compound arises as a degradation byproduct of Pilocarpic acid via oxidative pathways, distinguished by an additional hydroxyl substitution at the 6-position of the tropane nucleus. The sodium salt enhances aqueous solubility, facilitating its use as an HPLC reference standard for quantifying impurity profiles in parent drug formulations.
