Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 485.60 g/mol gives Ilaprazole Impurity 2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ilaprazole Impurity 2 (CAS 1360824-55-0) is a certified pharmaceutical impurity reference standard with the molecular formula C27H27N5O2S and a molecular weight of 485.60 g/mol.
Ilaprazole Impurity 2 (C27H27N5O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
As a certified reference material (CRM), Ilaprazole Impurity 2 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.
