Description

2-PHENYL-4H-BENZO[H]CHROMEN-4-ONE, also known as alpha-naphthylflavone or 2-phenyl-4H-naphtho(1,2-b)pyran-4-one, belongs to the class of organic compounds known as flavones. These are flavonoids with a structure based on the backbone of 2-phenylchromen-4-one (2-phenyl-1-benzopyran-4-one). Œ±-Naphthoflavone is found in Rhaponticum repens. Œ±-Naphthoflavone was first documented in 1969 (PMID: 5347522). 2-PHENYL-4H-BENZO[H]CHROMEN-4-ONE is an extremely weak basic (essentially neutral) compound (based on its pKa) (PMID: 143) (PMID: 14564451) (PMID: 17889503) (PMID: 22716253).
