Beschreibung

General description

Benedict′s reagents comprise of copper sulphate, sodium carbonate which functions as a mild alkali, and sodium citrate. It is quite stable. On boiling this reagent with glucose, it gives a white precipitate of cuprous thiocyanate. It is primarily used for the estimation of glucose in urine.

Application

Benedict′s reagent may be used during TLC analysis of mesocotyl methanol extracts during a study to evaluate sorghum resistance associated with accumulation of undetected toxic host metabolites.[1] It may also be also be used to synthesize an SEM image of the cubic shaped Cu₂O with smooth surface.[2]
