Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 406.86 g/mol gives Ertugliflozin Impurity 49 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ertugliflozin Impurity 49 (CAS CATO-C4X-301149), a pharmacopoeial impurity reference standard (molecular formula C21H23ClO6, MW 406.86 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Ertugliflozin Impurity 49 (C21H23ClO6) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 406.86 g/mol, it falls into the moderately-high-molecular-weight range. 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.
