Description
CATO manufactures Vonoprazan Impurity 269 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.
Vonoprazan Impurity 269 (CAS CATO-C4X-1020269) is a certified pharmaceutical impurity reference standard with the molecular formula C32H23F2N5O4S2 and a molecular weight of 643.68 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, Vonoprazan Impurity 269 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 643.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
