Description
As a certified reference material (CRM), Lansoprazole impurity 65 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.
CATO supplies Lansoprazole impurity 65 (CAS CATO-C4X-111365), a pharmacopoeial impurity reference standard (molecular formula C17H16F3N3OS, MW 367.39 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Lansoprazole impurity 65 (C17H16F3N3OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
