Chemical Structure

Keverprazan Impurity 1 CAS 2231094-87-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 432.47 g/mol gives Keverprazan Impurity 1 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Keverprazan Impurity 1 (CAS 2231094-87-2, C21H21FN2O5S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Keverprazan Impurity 1 (C21H21FN2O5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 Keverprazan Impurity 1 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.
