CATO supplies 5-oxo-2,3,4,5-tetrahydrobenzo[b]thiepin-8-yl pivalate (CAS 2226905-43-5), a certified reference material (molecular formula C15H18O3S, MW 278.37 g/mol) for analytical method development and quality control.
5-oxo-2,3,4,5-tetrahydrobenzo[b]thiepin-8-yl pivalate (C15H18O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
