Chemical Structure

Lansoprazole Impurity 18 CAS 1083100-26-8 chemical structure

Description

CATO supplies Lansoprazole Impurity 18 (CAS 1083100-26-8), a pharmacopoeial impurity reference standard (molecular formula C25H22F6N4O3S, MW 572.52 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C25H22F6N4O3S, Lansoprazole Impurity 18 contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 572.52 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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), Lansoprazole 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.
