Compared with other compounds in its class, the molecular weight of 349.40 g/mol gives 3-Oxo-2-(thiophen-2-ylmethyl)isoindolin-1-yl benzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Oxo-2-(thiophen-2-ylmethyl)isoindolin-1-yl benzoate (CAS 866008-22-2), a certified reference material (molecular formula C20H15NO3S, MW 349.40 g/mol) for analytical method development and quality control.
Based on its molecular formula C20H15NO3S, 3-Oxo-2-(thiophen-2-ylmethyl)isoindolin-1-yl benzoate 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 349.40 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.
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.
