Methyl 2-((3-oxo-1-phenyl-2,3-dihydro-1H-inden-4-yl)thio)acetate (CAS 337921-72-9) is a high-purity analytical reference standard with the molecular formula C18H16O3S and a molecular weight of 312.38 g/mol.
Methyl 2-((3-oxo-1-phenyl-2,3-dihydro-1H-inden-4-yl)thio)acetate (C18H16O3S) contains a steroid 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.
As a certified reference material (CRM), Methyl 2-((3-oxo-1-phenyl-2,3-dihydro-1H-inden-4-yl)thio)acetate 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.
