Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 493.51 g/mol gives Vonoprazan Fumarate Impurity 203 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Vonoprazan Fumarate Impurity 203 (CAS CATO-C4X-1020203) is a certified pharmaceutical impurity reference standard with the molecular formula C23H21F2N3C4H4O4 and a molecular weight of 493.51 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Vonoprazan Fumarate Impurity 203 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 493.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures Vonoprazan Fumarate Impurity 203 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
