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 4-Bromo-1,5-diphenylpenta-2,4-dien-1-one.
CATO supplies 4-Bromo-1,5-diphenylpenta-2,4-dien-1-one (CAS 324580-55-4), a certified reference material (molecular formula C17H13BrO, MW 313.19 g/mol) for analytical method development and quality control.
4-Bromo-1,5-diphenylpenta-2,4-dien-1-one (C17H13BrO) 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 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), 4-Bromo-1,5-diphenylpenta-2,4-dien-1-one 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.
