Chemical Structure
Description
CATO supplies (E)-4-(2-(3-chlorophenoxy)phenyl)but-3-en-2-one (CAS 478043-80-0), a certified reference material (molecular formula C16H13ClO2, MW 272.73 g/mol) for analytical method development and quality control.
(E)-4-(2-(3-chlorophenoxy)phenyl)but-3-en-2-one (C16H13ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. 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), (E)-4-(2-(3-chlorophenoxy)phenyl)but-3-en-2-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.
