Chemical Structure
Description
The occurrence of 3-Chloro-N-(3-chloro-4-(pyrimidin-2-yloxy)phenyl)benzenesulfonamide is closely related to a nitrogen-containing heterocyclic scaffold, 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-N-(3-chloro-4-(pyrimidin-2-yloxy)phenyl)benzenesulfonamide (CAS 823782-55-4), a certified reference material (molecular formula C16H11Cl2N3O3S, MW 396.25 g/mol) for analytical method development and quality control.
3-Chloro-N-(3-chloro-4-(pyrimidin-2-yloxy)phenyl)benzenesulfonamide (C16H11Cl2N3O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 3-Chloro-N-(3-chloro-4-(pyrimidin-2-yloxy)phenyl)benzenesulfonamide 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.
