Chemical Structure
Description
4-Methyl-N-((2,2,4-trimethyl-2,3-dihydrobenzofuran-7-yl)carbamoyl)benzenesulfonamide (CAS 866008-56-2) is a high-purity analytical reference standard with the molecular formula C19H22N2O4S and a molecular weight of 374.45 g/mol.
4-Methyl-N-((2,2,4-trimethyl-2,3-dihydrobenzofuran-7-yl)carbamoyl)benzenesulfonamide (C19H22N2O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
As a certified reference material (CRM), 4-Methyl-N-((2,2,4-trimethyl-2,3-dihydrobenzofuran-7-yl)carbamoyl)benzenesulfonamide 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.
