Chemical Structure
Description
Structurally, Pantoprazole Impurity 51 (C16H14ClF2N3O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 417.81 g/mol, it falls into the moderately-high-molecular-weight range. 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).
CATO supplies Pantoprazole Impurity 51 (CAS 812664-93-0), a pharmacopoeial impurity reference standard (molecular formula C16H14ClF2N3O4S, MW 417.81 g/mol) used for the identification and quantification of trace impurities in APIs.
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 Pantoprazole Impurity 51 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.
