Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 285.38 g/mol gives Dofetilide Impurity 7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Dofetilide Impurity 7 (CAS 115256-13-8), a certified reference material (molecular formula C17H23N3O, MW 285.38 g/mol) for analytical method development and quality control.
The molecular framework of Dofetilide Impurity 7 (C17H23N3O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Dofetilide Impurity 7 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.
