Description
CATO manufactures 3-Methoxy-N-methyldesloratadine-d4 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.
3-Methoxy-N-methyldesloratadine-d4 (CAS 1189445-21-3) is a high-purity analytical reference standard with the molecular formula C21H19D4ClN2O and a molecular weight of 358.90 g/mol.
3-Methoxy-N-methyldesloratadine-d4 (C21H19D4ClN2O) contains deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
