Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-{4-[(2E)-3-(2-Bromophenyl)prop-2-enoyl]phenyl}-1H-pyrrole-2,5-dione.
1-{4-[(2E)-3-(2-Bromophenyl)prop-2-enoyl]phenyl}-1H-pyrrole-2,5-dione (CAS 1365988-73-3), molecular formula C19H12BrNO3 and molecular weight 382.21 g/mol, is a CATO reference standard with documented purity and traceability.
1-{4-[(2E)-3-(2-Bromophenyl)prop-2-enoyl]phenyl}-1H-pyrrole-2,5-dione (C19H12BrNO3) 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. 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.
As a certified reference material (CRM), 1-{4-[(2E)-3-(2-Bromophenyl)prop-2-enoyl]phenyl}-1H-pyrrole-2,5-dione 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.
