Description
CATO supplies (E)-[2-(Benzenesulfonyl)-2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]ethylidene](methoxy)amine (CAS 338758-57-9), a certified reference material (molecular formula C15H12ClF3N2O3S, MW 392.78 g/mol) for analytical method development and quality control.
Structurally, (E)-[2-(Benzenesulfonyl)-2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]ethylidene](methoxy)amine (C15H12ClF3N2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 392.78 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
