142994-80-7 2-(1,3-Dioxo-1,3-dihydro-2H-isoindol-2-yl)-4,5,6,7-tetrahydro-1-benzothiophene-3-carbonitrile MFCD00107459 (CAS 142994-80-7), molecular formula C17H12N2O2S and molecular weight 308.35 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C17H12N2O2S, 142994-80-7 2-(1,3-Dioxo-1,3-dihydro-2H-isoindol-2-yl)-4,5,6,7-tetrahydro-1-benzothiophene-3-carbonitrile MFCD00107459 contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 308.35 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.
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.
