Description

Acetyl Empagliflozin Furanose Impurity is a process-related and/or degradative analog of empagliflozin distinguished by O-acetylation of the furanose-derived glycosidic scaffold. With molecular formula C31H35ClO11 and molecular weight 619.05 g/mol, it contains the aryl chlorinated C-aryl glucoside core and an additional acetate functionality that can arise from incomplete deprotection, acetyl transfer, or downstream transformation of protected intermediates. Its structural assessment is relevant to impurity profiling under ICH Q3A/Q3B. Trace-level measurement typically requires LC-MS/MS or high-resolution LC-MS, supported by orthogonal HPLC-UV or NMR characterization for isomer discrimination.
