Building Blocks

7-Amino-4-trifluoromethylcoumarin. This dye is used to prepare peptidase substrates and synthesis of substrates for the fluorometric assay of proteolytic enzymes in biological fluids.

This dye is used to prepare peptidase substrates and synthesis of substrates for the fluorometric assay of proteolytic enzymes in biological fluids. Amide in these peptidase substrates has shorter-wavelength absorption and emission spectra than the amine.
