Chemical Structure
Description
The occurrence of N-((2-benzoyl-5-chlorophenyl)(methyl)carbamoyl)-4-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.
N-((2-benzoyl-5-chlorophenyl)(methyl)carbamoyl)-4-methylbenzenesulfonamide (CAS 1024078-05-4) is a high-purity analytical reference standard with the molecular formula C22H19ClN2O4S and a molecular weight of 442.92 g/mol.
N-((2-benzoyl-5-chlorophenyl)(methyl)carbamoyl)-4-methylbenzenesulfonamide (C22H19ClN2O4S) contains a flavonoid core, 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. 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.
As a certified reference material (CRM), N-((2-benzoyl-5-chlorophenyl)(methyl)carbamoyl)-4-methylbenzenesulfonamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
