(S)-4-(4-Fluoro-2-formylphenyl)-1-(tert-butoxy-carbonyl)piperazine-2-carboxylic acid 1787206-21-6 (CAS 1787206-21-6), molecular formula C17H21FN2O5 and molecular weight 352.36 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-4-(4-Fluoro-2-formylphenyl)-1-(tert-butoxy-carbonyl)piperazine-2-carboxylic acid 1787206-21-6 (C17H21FN2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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.
