CATO supplies N-[4-Chloro-2-hydroxy-3-[(piperazin-1-yl)sulfonyl]phenyl]-N'-(2-chloro-3-fluorophenyl)urea p-toluene (CAS 960495-43-6), a certified reference material (molecular formula C17H17Cl2FN4O4SC7H8O3S, MW 635.50 g/mol) for analytical method development and quality control.
N-[4-Chloro-2-hydroxy-3-[(piperazin-1-yl)sulfonyl]phenyl]-N'-(2-chloro-3-fluorophenyl)urea p-toluene (C17H17Cl2FN4O4SC7H8O3S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures N-[4-Chloro-2-hydroxy-3-[(piperazin-1-yl)sulfonyl]phenyl]-N'-(2-chloro-3-fluorophenyl)urea p-toluene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
