2-nitrophenyl 2,3,4,6-tetra-O-acetyl-beta-D-galactopyranoside

Description:

2-Nitrophenyl 2,3,4,6-tetra-O-acetyl-beta-D-galactopyranoside is a chemical compound that serves as a glycoside, specifically a derivative of galactose. It features a galactopyranoside structure where the hydroxyl groups at positions 2, 3, 4, and 6 are acetylated, enhancing its stability and solubility in organic solvents. The presence of the 2-nitrophenyl group contributes to its utility in biochemical applications, particularly as a substrate in enzymatic assays, where it can be hydrolyzed by galactosidases. This compound is typically a white to off-white crystalline solid, and it is soluble in polar organic solvents. Its acetyl groups can be removed under specific conditions, allowing for the regeneration of the free hydroxyl groups on the galactose moiety. The compound is used in various research applications, including studies of carbohydrate metabolism and enzyme kinetics. Safety precautions should be observed when handling this compound, as it may pose health risks if ingested or inhaled.
