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 (1E,4E)-1,5-Bis(4-bromophenyl)penta-1,4-dien-3-one.
(1E,4E)-1,5-Bis(4-bromophenyl)penta-1,4-dien-3-one (CAS 115846-95-2), molecular formula C17H12Br2O and molecular weight 392.08 g/mol, is a CATO reference standard with documented purity and traceability.
(1E,4E)-1,5-Bis(4-bromophenyl)penta-1,4-dien-3-one (C17H12Br2O) contains a steroid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
