Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 409.44 g/mol gives 1-(4-(4-Amino-6,7-dimethoxyquinazolin-2-yl)piperazin-1-yl)-3-(furan-3-yl)prop-2-en-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(4-(4-Amino-6,7-dimethoxyquinazolin-2-yl)piperazin-1-yl)-3-(furan-3-yl)prop-2-en-1-one (CAS 70842-93-2) is a high-purity analytical reference standard with the molecular formula C21H23N5O4 and a molecular weight of 409.44 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 1-(4-(4-Amino-6,7-dimethoxyquinazolin-2-yl)piperazin-1-yl)-3-(furan-3-yl)prop-2-en-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 409.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
