CATO supplies (5R,7R)-3-bromo-2-(4-fluorophenyl)-5,7-dimethyl-6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazine (CAS 1429893-32-2), a certified reference material (molecular formula C14H14BrFN2O, MW 325.18 g/mol) for analytical method development and quality control.
(5R,7R)-3-bromo-2-(4-fluorophenyl)-5,7-dimethyl-6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazine (C14H14BrFN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine 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.
CATO manufactures (5R,7R)-3-bromo-2-(4-fluorophenyl)-5,7-dimethyl-6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazine 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.
