Empagliflozin Intermediate 2

Empagliflozin Intermediate 2 is a halogenated aromatic compound featuring a bromine and chlorine substituent on a substituted benzene ring, integrated into the synthetic pathway of Empagliflozin. Its structural motif includes a ketone functionality adjacent to a methoxy group, diverging from the parent drug through strategic halogenation for controlled reactivity. This intermediate serves as a critical HPLC reference standard for quantifying process-related impurities during active pharmaceutical ingredient manufacturing.
