Description
CATO manufactures Desmopressin Tyrosine Oxidation Impurity 1 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.
CATO supplies Desmopressin Tyrosine Oxidation Impurity 1 (CAS CATO-C4X-221518), a pharmacopoeial impurity reference standard (molecular formula C46H64N14O13S2C2HF3O2, MW 1199.25 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C46H64N14O13S2C2HF3O2, Desmopressin Tyrosine Oxidation Impurity 1 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 1199.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
