Chemical Structure

Buspirone Impurity 23 CAS 20261-27-2 chemical structure

Description

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.

Buspirone Impurity 23 (CAS 20261-27-2) is a certified pharmaceutical impurity reference standard with the molecular formula C12H26N4HCl and a molecular weight of 262.83 g/mol.

Structurally, Buspirone Impurity 23 (C12H26N4HCl) contains chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 262.83 g/mol, it falls into the medium-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.

CATO manufactures Buspirone Impurity 23 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.
