N-(2-(4-(Benzo[d][1,3]dioxol-5-yl)-3-(6-methylpyridin-2-yl)-1H-pyrazol-1-yl)ethyl)methanesulfonamide (CAS 746666-87-5) is a high-purity analytical reference standard with the molecular formula C19H20N4O4S and a molecular weight of 400.45 g/mol.
The molecular framework of N-(2-(4-(Benzo[d][1,3]dioxol-5-yl)-3-(6-methylpyridin-2-yl)-1H-pyrazol-1-yl)ethyl)methanesulfonamide (C19H20N4O4S) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), N-(2-(4-(Benzo[d][1,3]dioxol-5-yl)-3-(6-methylpyridin-2-yl)-1H-pyrazol-1-yl)ethyl)methanesulfonamide 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.
