Description
CATO supplies N-(4-Bromophenyl)-4-(o-tolyloxy)butanamide (CAS 385373-45-5), a certified reference material (molecular formula C17H18BrNO2, MW 348.23 g/mol) for analytical method development and quality control.
N-(4-Bromophenyl)-4-(o-tolyloxy)butanamide (C17H18BrNO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
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 N-(4-Bromophenyl)-4-(o-tolyloxy)butanamide 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.
