Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(Furan-2-ylmethyl)-6,7-dimethoxy-2-((3-(trifluoromethyl)benzyl)thio)quinazolin-4(3H)-imine.
3-(Furan-2-ylmethyl)-6,7-dimethoxy-2-((3-(trifluoromethyl)benzyl)thio)quinazolin-4(3H)-imine (CAS 691858-04-5) is a high-purity analytical reference standard with the molecular formula C23H20F3N3O3S and a molecular weight of 475.48 g/mol.
3-(Furan-2-ylmethyl)-6,7-dimethoxy-2-((3-(trifluoromethyl)benzyl)thio)quinazolin-4(3H)-imine (C23H20F3N3O3S) contains a steroid core, an amide group, a sulfone 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. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
