Compared with other compounds in its class, the molecular weight of 395.20 g/mol gives S-Benzyl 4-methylbenzenesulfonothioate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
S-Benzyl 4-methylbenzenesulfonothioate (CAS 16601-02-8), molecular formula C20H22NO2BF4 and molecular weight 395.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, S-Benzyl 4-methylbenzenesulfonothioate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 395.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
