CATO supplies 7-(3,4-Diethoxyphenyl)-2-[4-(2-fluorophenyl)piperazin-1-yl]-3H,4H-thieno[3,2-d]pyrimidin-4-one (CAS 1243105-27-2), a certified reference material (molecular formula C26H27FN4O3S, MW 494.58 g/mol) for analytical method development and quality control.
7-(3,4-Diethoxyphenyl)-2-[4-(2-fluorophenyl)piperazin-1-yl]-3H,4H-thieno[3,2-d]pyrimidin-4-one (C26H27FN4O3S) 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. 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.
