Description
The occurrence of 3-Chloro-4-(2-chloro-4-(3,5-dioxo-4,5-dihydro-1,2,4-triazin-2(3H)-yl)-6-methylphenoxy)-N-ethyl-N-methylbenzenesulfonamide is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Chloro-4-(2-chloro-4-(3,5-dioxo-4,5-dihydro-1,2,4-triazin-2(3H)-yl)-6-methylphenoxy)-N-ethyl-N-methylbenzenesulfonamide (CAS 55369-98-7), a certified reference material (molecular formula C19H18Cl2N4O5S, MW 485.34 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 3-Chloro-4-(2-chloro-4-(3,5-dioxo-4,5-dihydro-1,2,4-triazin-2(3H)-yl)-6-methylphenoxy)-N-ethyl-N-methylbenzenesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 485.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
