Description
CATO supplies Salbutamol Impurity 60 (CAS 238762-31-7), a pharmacopoeial impurity reference standard (molecular formula C16H25NO3, MW 279.37 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C16H25NO3, Salbutamol Impurity 60 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 279.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Salbutamol Impurity 60 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.
