Quetiapine EP Impurity U CAS 5786-26-5 chemical structure

Description

Quetiapine EP Impurity U (CAS 5786-26-5) is a certified pharmaceutical impurity reference standard with the molecular formula C13H10N2S and a molecular weight of 226.30 g/mol.

Based on its molecular formula C13H10N2S, Quetiapine EP Impurity U contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 226.30 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.

CATO manufactures Quetiapine EP Impurity U under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
