Chemical Structure

Ipragliflozin Impurity 12 CAS CATO-C4X-188512 chemical structure

Description

Ipragliflozin Impurity 12 (C21H21FO7S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a process- or degradation-related impurity, Ipragliflozin Impurity 12 (CAS CATO-C4X-188512, C21H21FO7S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

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.
