(S)-tert-Butyl 2-((4-chloro-2-fluoro-5-((3-phenylprop-2-yn-1-yl)oxy)phenyl)carbamoyl)pyrrolidine-1-carboxylate (CAS 1464137-29-8) is a high-purity analytical reference standard with the molecular formula C25H26ClFN2O4 and a molecular weight of 472.94 g/mol.
(S)-tert-Butyl 2-((4-chloro-2-fluoro-5-((3-phenylprop-2-yn-1-yl)oxy)phenyl)carbamoyl)pyrrolidine-1-carboxylate (C25H26ClFN2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
