Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
【停用，管制】1’-Hydroxy Midazolam-13C3 (CAS 1189677-14-2) is a high-purity analytical reference standard with the molecular formula C15[13C]3H13ClFN3O and a molecular weight of 344.74 g/mol.
【停用，管制】1’-Hydroxy Midazolam-13C3 (C15[13C]3H13ClFN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/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.
CATO manufactures 【停用，管制】1’-Hydroxy Midazolam-13C3 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.
