3-[(4-methoxyphenyl)amino]-1lambda6-thiolane-1,1-dione CAS 303992-20-3

Description

Compared with other compounds in its class, the molecular weight of 241.31 g/mol gives 3-[(4-methoxyphenyl)amino]-1lambda6-thiolane-1,1-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-[(4-methoxyphenyl)amino]-1lambda6-thiolane-1,1-dione (CAS 303992-20-3) is a high-purity analytical reference standard with the molecular formula C11H15NO3S and a molecular weight of 241.31 g/mol.

3-[(4-methoxyphenyl)amino]-1lambda6-thiolane-1,1-dione (C11H15NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.

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.
