7-Hydroxy Quetiapine EP Impurity B CAS 232597-73-8

Description

Compared with other compounds in its class, the molecular weight of 311.40 g/mol gives 7-Hydroxy Quetiapine EP Impurity B distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 7-Hydroxy Quetiapine EP Impurity B (CAS 232597-73-8), a pharmacopoeial impurity reference standard (molecular formula C17H17N3OS, MW 311.40 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, 7-Hydroxy Quetiapine EP Impurity B (C17H17N3OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 311.40 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 7-Hydroxy Quetiapine EP Impurity B 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.
