Description

Phenylephrine Impurity 9, also described as the phenylephrine citrate adduct, is a stoichiometric association product rather than a discrete degradant class. With molecular formula C15H19NO8 and molecular weight 341.31 g/mol, it reflects salt or complex formation between phenylephrine and citrate under acidic processing or storage conditions. Its presence may indicate formulation interaction, crystallization behavior, or carryover from citrate-containing media. Characterization generally requires orthogonal LC-MS/MS and high-resolution LC-MS, with confirmation by NMR when isolated. In impurity profiling, its chromatographic behavior must be distinguished from related phenylephrine species and counterion artifacts.
