Coumarin 151 Chemical Properties,Uses,Production

Chemical Properties

Coumarin 151 is yellow powder

Uses

Coumarin 151  is used to prepare peptidase substrates and for the synthesis of substrates for the fluorometric assay of proteolytic enzymes in biological fluids.

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.
