P-NITROPHENYL 2-ACETAMIDO-2-DEOXY-ALPHA-D-GALACTOPYRANOSIDE Usage And Synthesis

Description

N-acetyl-D-galactosaminidase catalyzes the cleavage of N-acetylglucosamine (GlcNAc), the monomeric unit of the polymer chitin. 4-Nitrophenyl-N-acetyl-α-D-galactosaminide can be used as a chromogenic substrate for N-acetyl-D-galactosaminidase, generating a yellow solution upon cleavage.

Chemical Properties

White Solid

Uses

p-Nitrophenyl 2-Acetamido-2-deoxy-α-D-galactopyranoside (cas# 23646-68-6) is a compound useful in organic synthesis.

Definition

ChEBI: An N-acetyl-alpha-D-galactosaminide having a 4-nitrophenyl substituent at the anomeric position.
