Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (E)-N-(4-bromo-3-methylphenyl)-3-(4-isobutylphenyl)acrylamide (CAS 939893-42-2), a certified reference material (molecular formula C20H22BrNO, MW 372.30 g/mol) for analytical method development and quality control.
(E)-N-(4-bromo-3-methylphenyl)-3-(4-isobutylphenyl)acrylamide (C20H22BrNO) 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; 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.
As a certified reference material (CRM), (E)-N-(4-bromo-3-methylphenyl)-3-(4-isobutylphenyl)acrylamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
