Chemical Structure
Description
The occurrence of 4-(3-(2-Cyano-4,5-dimethoxyphenyl)thioureido)-N,N-dimethylbenzenesulfonamide is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(3-(2-Cyano-4,5-dimethoxyphenyl)thioureido)-N,N-dimethylbenzenesulfonamide (CAS 692287-56-2), molecular formula C18H20N4O4S2 and molecular weight 420.51 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(3-(2-Cyano-4,5-dimethoxyphenyl)thioureido)-N,N-dimethylbenzenesulfonamide (C18H20N4O4S2) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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 4-(3-(2-Cyano-4,5-dimethoxyphenyl)thioureido)-N,N-dimethylbenzenesulfonamide 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.
