Abstract
An analytical method for the determination of hydrogen peroxide utilizes a hydrazide or a hydrazine substituted with one or more electron withdrawing groups. The hydrazides or hydrazines react with phenolic color couplers in the presence of hydrogen peroxide and a peroxidative compound to form a dye detectable at a wavelength of 600 nm or greater. These materials can also be used to assay analytes, such as glucose and cholesterol, which can react to produce hydrogen peroxide.
