Carbetocin Impurity 4 is a structurally related peptide species generated during carbetocin synthesis or storage. Variations in side-chain or ring connectivity influence folding and chromatographic behavior. Researchers characterize it using LC-MS and NMR to ensure method selectivity. Applications include process-control support, impurity-specification definition, and structure-purity correlation.
