Description
Alfa Chemistry offers high-purity 8-Methoxy-4-methylbenzo[g]coumarin products for various research purposes. Please contact us by email if you do not find the specification you are looking for on this page.
The unique fluorescence properties of a coumarin analog, 8-methoxy-4-methylbenzo[g]coumarin (MMBC). MMBC is almost nonfluorescent in aprotic solvents, whereas it strongly fluoresces at long wavelengths in protic solvents. In the protic solvents, MMBC has a large Stokes shift. These unique features are convenient for developments of new fluorogenic sensors and devices.

Features And Benefits
Coumarins are aromatic lactone compounds, many of which are found in natural plants. Coumarin compounds having an electron donating group at the 7-position show strong light absorption and emission, whereas unsubstituted coumarin compounds hardly emit light. This is because intramolecular charge transfer occurs when both electron-donating and electron-withdrawing groups are present in the coumarin molecule. The introduction of groups at the 3- or 4-position largely controls the wavelength of light absorption and emission. Furthermore, the introduction of electron-withdrawing groups at these positions can enhance the luminescence intensity.
