Based on its molecular formula C17H18O2S, 3-(tert-Butyl)-4,9-dimethyl-7H-furo[2,3-f]chromene-7-thione contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 286.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
3-(tert-Butyl)-4,9-dimethyl-7H-furo[2,3-f]chromene-7-thione (CAS 951975-11-4) is a high-purity analytical reference standard with the molecular formula C17H18O2S and a molecular weight of 286.39 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
