Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
n-(4-Bromophenyl)-2-(4-(4-fluorophenyl)piperazin-1-yl)acetamide (CAS 303091-47-6), molecular formula C18H19BrFN3O and molecular weight 392.27 g/mol, is a CATO reference standard with documented purity and traceability.
n-(4-Bromophenyl)-2-(4-(4-fluorophenyl)piperazin-1-yl)acetamide (C18H19BrFN3O) contains a steroid core, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures n-(4-Bromophenyl)-2-(4-(4-fluorophenyl)piperazin-1-yl)acetamide 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.
