Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 2-Methyl-6-{2-[5-(toluene-4-sulfonyl)-thiophen-2-yl]-vinyl}-benzoic acid methyl ester (CAS 1171924-15-4), a certified reference material (molecular formula C22H20O4S2, MW 412.52 g/mol) for analytical method development and quality control.
2-Methyl-6-{2-[5-(toluene-4-sulfonyl)-thiophen-2-yl]-vinyl}-benzoic acid methyl ester (C22H20O4S2) contains a flavonoid core, a sulfone group, 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.
