Chemical Structure

Regadenoson Impurity 24 CAS 50447-10-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 311.29 g/mol gives Regadenoson Impurity 24 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Regadenoson Impurity 24 (CAS 50447-10-4) is a certified pharmaceutical impurity reference standard with the molecular formula C12H17N5O5 and a molecular weight of 311.29 g/mol.

Based on its molecular formula C12H17N5O5, Regadenoson Impurity 24 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 311.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Regadenoson Impurity 24 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.
