7-(trifluoromethyl)quinazolin-4(3H)-one; CAS No.: 16499-58-4; 7-(trifluoromethyl)quinazolin-4(3H)-one. PROPERTIES: 7-(trifluoromethyl)quinazolin-4(3H)-one is a crystalline powder with molecular formula C9H5F3N2O. It has a melting point between 200-205 C and exhibits limited solubility in common organic solvents. The compound is light-sensitive and should be stored in amber glassware at 2-8 C. Safety precautions include wearing protective clothing due to its potential to cause skin burns and using explosion-proof ventilation due to its explosive nature when exposed to heat. APPLICATIONS: This trifluoromethyl-substituted quinazolinone is used in the development of anticancer prodrugs. The quinazolinone structure provides critical interactions with kinase enzymes as reported in cancer research literature. In materials science, 7-(trifluoromethyl)quinazolin-4(3H)-one serves as a building block for creating electron-transport materials. According to materials chemistry journals, the electron-withdrawing trifluoromethyl group improves charge transport properties while the quinazolinone scaffold provides structural rigidity.
