Description
CATO supplies Atosiban Impurity 88 (CAS CATO-C4X-229388), a pharmacopoeial impurity reference standard (molecular formula C12H19NO5, MW 257.28 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C12H19NO5, Atosiban Impurity 88 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 257.28 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 Atosiban Impurity 88 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.
