2-(Dimethyl (oxo)-λ6-sulfanylidene)-1-phenylethan-1-one CAS 20718-17-6

Description

Compared with other compounds in its class, the molecular weight of 196.27 g/mol gives 2-(Dimethyl (oxo)-λ6-sulfanylidene)-1-phenylethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(Dimethyl (oxo)-λ6-sulfanylidene)-1-phenylethan-1-one (CAS 20718-17-6), molecular formula C10H12O2S and molecular weight 196.27 g/mol, is a CATO reference standard with documented purity and traceability.

2-(Dimethyl (oxo)-λ6-sulfanylidene)-1-phenylethan-1-one (C10H12O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
