CATO supplies 4,4'-(2,2-Diphenylethene-1,1-diyl)diphenol (CAS 919789-77-8), a certified reference material (molecular formula C26H20O2, MW 364.44 g/mol) for analytical method development and quality control.
4,4'-(2,2-Diphenylethene-1,1-diyl)diphenol (C26H20O2) contains a steroid core, a hydroxyl group, an ether linkage. 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.
