Chemical Structure

Dapagliflozin Impurity 55 CAS CATO-C4X-113855 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 250.32 g/mol gives Dapagliflozin Impurity 55 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Dapagliflozin Impurity 55 (CAS CATO-C4X-113855) is a certified pharmaceutical impurity reference standard with the molecular formula C9H18O6Si and a molecular weight of 250.32 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Dapagliflozin Impurity 55 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 250.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
