Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 275.31 g/mol gives N-cyclohexyl-2,6-difluorobenzenesulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-cyclohexyl-2,6-difluorobenzenesulfonamide (CAS 913490-68-3), molecular formula C12H15F2NO2S and molecular weight 275.31 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N-cyclohexyl-2,6-difluorobenzenesulfonamide (C12H15F2NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 275.31 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
