CAS 87331-48-4: 1H,5H,11H-[1]Benzopyrano[6,7,8-ij]quinolizin-11-one,2,3,6,7-tetrahydro-10-(methylsulfonyl)- (9CI)

Coumarin 498 is a fluorescent dye that is used in biomedical research to measure the movement of proteins and other molecules in living cells. Coumarin 498 can be used to study the effects of radiation on cells by measuring the level of fluorescence under different conditions. Coumarin 498 has been shown to bind with aliphatic hydrocarbons, such as those found in cell membranes. It has also been shown to modulate the activity of enzymes and other biochemical processes. Coumarin 498 is an acceptor molecule for electrons, which allows it to react with oxygen molecules and form reactive oxygen species (ROS), leading to oxidative stress.
