Description

Hyoscine Butylbromide EP Impurity G, also described as Hyoscine Apo-N-Butyl Impurity, is a structurally defined tropane alkaloid derivative with molecular formula C21H28NO3 and molecular weight 342.45 g/mol. It is consistent with a dequaternized or rearranged degradation product arising from cleavage or elimination processes affecting the butylated scopolamine framework during synthesis or stress conditions. As a non-nitrosamine impurity, its regulatory relevance lies in impurity profiling and specification setting under pharmacopeial expectations. Reliable detection typically requires LC-MS/MS for identity confirmation and trace quantification, with LC-HRMS and orthogonal chromatographic separation supporting peak assignment and impurity discrimination.
