Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 478.92 g/mol gives Ertugliflozin impurity 32 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ertugliflozin impurity 32 (CAS 1298086-20-0) is a certified pharmaceutical impurity reference standard with the molecular formula C24H27ClO8 and a molecular weight of 478.92 g/mol.
Structurally, Ertugliflozin impurity 32 (C24H27ClO8) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 478.92 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
