Esmolol Impurity 77 CAS CATO-C4X-189177

Description

Compared with other compounds in its class, the molecular weight of 253.30 g/mol gives Esmolol Impurity 77 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Esmolol Impurity 77 (CAS CATO-C4X-189177), a pharmacopoeial impurity reference standard (molecular formula C15H15N3O, MW 253.30 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C15H15N3O, Esmolol Impurity 77 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 253.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Esmolol Impurity 77 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.
