3-羟基黄酮,98% CAS号：577-85-5

3-Hydroxyflavone is a chemical compound. It is the backbone of allflavonols, a type of flavonoid. It is a synthetic compound, whichis not found naturally in plants. It serves as a model molecule asit possesses an excited-state intramolecular proton transfer(ESIPT) effect to serve as a fluorescent probe to study membranesfor example or intermembrane proteins. The green tautomer emission(λmax ≈ 524nm) and blue-violet normal emission (λmax ≈ 400nm)originate from two different ground state populations of 3HFmolecules. The phenomenon also exists in natural flavonols.Although 3-hydroxyflavone is almost insoluble in water, its a (hence bio-availability) can be increased byencapsulation in cyclodextrin cavitiies
