N-(2-Methyl-1-(pyridin-2-ylthio)propan-2-yl)benzenesulfonamide (CAS 831243-91-5), molecular formula C15H18N2O2S2 and molecular weight 322.45 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N-(2-Methyl-1-(pyridin-2-ylthio)propan-2-yl)benzenesulfonamide (C15H18N2O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 322.45 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
