2-Chloro-4-nitrophenyl alpha-D-maltotrioside

2-Chloro-4-nitrophenyl alpha-D-maltotrioside is a colorimetric substrate for alpha-amylases. Upon hydrolysis by alpha-amylases, 2-chloro-4-nitrophenol is released which can be quantified by colorimetric detection at 405 nm as a measure of enzyme activity. 2-Chloro-4-nitrophenyl alpha-D-maltotrioside has been used to characterize the activity of human pancreatic or salivary amylase.Formal Name: 2-chloro-4-nitrophenyl O-alpha-D-glucopyranosyl-(1->4)-O-alpha-D-glucopyranosyl-(1->4)-alpha-D-glucopyranoside.
