chromone
Molecular formula :
CAS :

nature : names benzo - γ - pyron. Colorless acicular crystals. 59 ° C melting point. Soluble ethanol, ethyl ether, chloroform, benzene and hot water. May sublimation. Concentrated sulfuric acid soluble fluorescent purple. With potassium permanganate role in salicylic acid. O dihydroxyacetophenone and Ethyl in the presence of alkali condensation products via acid catalysis from closed-loop system. Benzo - γ - pyron derivatives widely exist in plants, and some colored material, it called for chromone mother.
