Chemical Structure
Description
4-[(2E)-3-(Thiophen-2-yl)prop-2-enoyl]phenyl 2,5-dichlorobenzene-1-sulfonate (C19H12Cl2O4S2) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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.
4-[(2E)-3-(Thiophen-2-yl)prop-2-enoyl]phenyl 2,5-dichlorobenzene-1-sulfonate (CAS 297150-16-4) is a high-purity analytical reference standard with the molecular formula C19H12Cl2O4S2 and a molecular weight of 439.33 g/mol.
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-[(2E)-3-(Thiophen-2-yl)prop-2-enoyl]phenyl 2,5-dichlorobenzene-1-sulfonate 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.
