Definition
ChEBI: 7-amino-4-(trifluoromethyl)coumarin is a member of 7-aminocoumarins. It has a role as a fluorochrome.
Purification Methods
Purify the coumarin by column chromatography on a C18 column, elute with acetonitrile/0.01M H2O/HCl (1:1), and recrystallise it from isopropanol. Alternatively, it is eluted from a silica gel column with CH2Cl2, or by extracting a CH2Cl2 solution (4g/L) with 1M aqueous NaOH (3 x 0.1L), followed by drying (MgSO4), filtration and evaporation.
