8-二羟基-4-甲基香豆素 - Reference Information
| biological activity | 4-methylketene is a precursor for the synthesis of 4-methylcoumarin derivatives. 4-methylnaphnetin has potent and selective anti-proliferative and apoptosis-inducing effects on several tumor cell lines. 4-methylldaphnetin has the effect of scavenging free radicals and has a strong inhibitory effect on membrane lipid peroxidation. |
| Use | can be used as a fluorescent sensor to monitor the consumption of boric acid in Suzuki cross-coupling reactions. Using a standard hand-held long-wave UV lamp (365nm), fluorescence can be easily found to the naked eye. |
