Chemical Structure

Empagliflozin Impurity 153 CAS 219823-47-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 242.29 g/mol gives Empagliflozin Impurity 153 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Empagliflozin Impurity 153 (CAS 219823-47-9) is a certified pharmaceutical impurity reference standard with the molecular formula C11H14O4S and a molecular weight of 242.29 g/mol.

Based on its molecular formula C11H14O4S, Empagliflozin Impurity 153 contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 242.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
