3-acetyl-2H-chromen-2-one - Reference Information
| overview | coumarin has a large molar extinction coefficient and quantum yield. it is a very important green fluorescent dye and is used for luminescent materials, chemical sensors and biomolecules after modification. In recent years, the research on the detection of cysteine in living cells by fluorescence enhancement effect has been continuously developed. 3-Acetyl hydroxycoumarin is also called 3-acetyl coumarin; 8-acetyl -6, 7-dimethoxycoumarin, which is a white solid at room temperature with a special fragrance, and is often used as an intermediate in pharmaceutical and chemical synthesis At the same time, 3-acetyl hydroxycoumarin, as an important representative of coumarin derivatives, is widely used in fluorescent probe detection, and has the advantages of low price and high sensitivity. |
