3-(5-bromo-2-methoxyphenyl)-2-(phenylsulfonyl)prop-2-enenitrile (CAS 891956-54-0), molecular formula C16H12BrNO3S and molecular weight 378.24 g/mol, is a CATO reference standard with documented purity and traceability.
3-(5-bromo-2-methoxyphenyl)-2-(phenylsulfonyl)prop-2-enenitrile (C16H12BrNO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
