Chemical Structure
Description
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.
3-(2-Chlorophenyl)-2-(2-(6-((diethylamino)methyl)pyridin-2-yl)vinyl)-6-fluoroquinazolin-4(3H)-one hydrochloride (CAS 1785666-59-2), molecular formula C26H24ClFN4OHCl and molecular weight 499.41 g/mol, is a CATO reference standard with documented purity and traceability.
3-(2-Chlorophenyl)-2-(2-(6-((diethylamino)methyl)pyridin-2-yl)vinyl)-6-fluoroquinazolin-4(3H)-one hydrochloride (C26H24ClFN4OHCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
