2-((6-Bromo-3-(furan-2-ylmethyl)-4-oxo-3,4-dihydroquinazolin-2-yl)thio)-N-(2-cyano-3-methylbutan-2-yl)acetamide (CAS 786726-43-0) is a high-purity analytical reference standard with the molecular formula C21H21BrN4O3S and a molecular weight of 489.39 g/mol.
2-((6-Bromo-3-(furan-2-ylmethyl)-4-oxo-3,4-dihydroquinazolin-2-yl)thio)-N-(2-cyano-3-methylbutan-2-yl)acetamide (C21H21BrN4O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine 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.
