Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 159.18 g/mol gives Dronedarone Impurity 74 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dronedarone Impurity 74 (CAS 948015-51-8) is a certified pharmaceutical impurity reference standard with the molecular formula C7H13NO3 and a molecular weight of 159.18 g/mol.
Structurally, Dronedarone Impurity 74 (C7H13NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 159.18 g/mol, it falls into the medium-molecular-weight range. 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 Dronedarone Impurity 74 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.
