Known Application

2-chloro-4-nitrophenylmaltotrioside (CNPG3) is commonly used as a substrate for α-amylase (alpha-amyl hydrolase) assays. In this context, CNPG3 serves as a chromogenic substrate, meaning that it undergoes a color change upon hydrolysis by α-amylase, allowing for the measurement of enzyme activity.
1：CNPG3 is highly sensitive to α-amylase activity. Upon hydrolysis, it releases a 2-chloro-4-nitrophenyl (CNP) group, which produces a colored product. The intensity of the color change is directly proportional to the amount of CNP released, allowing for precise measurement of enzyme activity.

2： CNPG3 is relatively stable, making it suitable for use in enzyme assays over a wide range of conditions, including varying pH and temperature.
