Chemical Structure
Description
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, Pantoprazole Impurity 18 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 534.53 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.
CATO supplies Pantoprazole Impurity 18 (CAS CATO-C4X-139918), a pharmacopoeial impurity reference standard (molecular formula C24H24F2N4O6S, MW 534.53 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.
As a certified reference material (CRM), Pantoprazole Impurity 18 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
