Chemical Structure

Sarpogrelate Impurity 20 CAS 1659311-39-3 chemical structure

Description

The occurrence of Sarpogrelate Impurity 20 is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Sarpogrelate Impurity 20 (CAS 1659311-39-3) is a certified pharmaceutical impurity reference standard with the molecular formula C12H17NO3 and a molecular weight of 223.27 g/mol.

Based on its molecular formula C12H17NO3, Sarpogrelate Impurity 20 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 223.27 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).

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), Sarpogrelate Impurity 20 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.
