2-Chloro-4-nitrophenyl-α-L-fucopy ranoside CAS:157843-41-9

2-Chloro-4-nitrophenyl-alpha-L-fucopyranoside is commonly used in biochemistry and molecular biology as a substrate for detecting and quantifying the activity of enzymes called fucosidases. Fucosidases are enzymes that cleave fucose residues from glycoconjugates, which are essential components of cell surface proteins and play important roles in many cellular processes.

The compound is non-fluorescent, but once it is cleaved by fucosidase, it yields a highly fluorescent product that can be easily detected and measured. This enzymatic conversion enables researchers to study the activity and specificity of fucosidases, as well as to investigate the dynamics of fucose metabolism.

In addition to enzyme activity studies, 2-Chloro-4-nitrophenyl-alpha-L-fucopyranoside has also been used for the detection and quantification of fucose residues in samples.
