Introduction of 2169998-23-4 :

Dapagliflozin keto impurity (Oxo-dapagliflozin) is an oxo metabolite and related impurity of Dapagliflozin (HY-10450). Dapagliflozin keto impurity can be characterized by 1H NMR, 13C NMR and HRMS, and can be used in studies related to Dapagliflozin impurities and metabolites[1]. In Vitro:Dapagliflozin keto impurity (Oxo-dapagliflozin) is an off-white amorphous solid, which is prepared via multi-step chemical synthesis using methoxyoxo-dapagliflozin as the starting material with a yield of 80%. Its structure is confirmed by NMR and HRMS[1].
Dapagliflozin keto impurity is obtained by hydrolyzing tetraacetyl oxo dapagliflozin with LiOH·H2O. The reaction proceeds at 20-30°C for 16 h, with a yield of 84%[1].
