(2R)-4-{6-ethynyl-3-oxo-1H,2H,3H-pyrrolo[1,2-c]imidazol-2-yl}-2-methanesulfonyl-2-methyl-N-(oxan-2-yloxy)butanamide (CAS 1808271-29-5) is a high-purity analytical reference standard with the molecular formula C19H25N3O6S and a molecular weight of 423.48 g/mol.
The molecular framework of (2R)-4-{6-ethynyl-3-oxo-1H,2H,3H-pyrrolo[1,2-c]imidazol-2-yl}-2-methanesulfonyl-2-methyl-N-(oxan-2-yloxy)butanamide (C19H25N3O6S) 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), (2R)-4-{6-ethynyl-3-oxo-1H,2H,3H-pyrrolo[1,2-c]imidazol-2-yl}-2-methanesulfonyl-2-methyl-N-(oxan-2-yloxy)butanamide 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.
