A simple spectrophotometric determination of formaldehyde and other aldehydes: application to periodate-oxidized
Analytical Biochemistry
|October 15, 1983
Abstract:
A simple, rapid, and sensitive spectrophotometric assay procedure for the determination of as low as 2 microM solutions of formaldehyde and acetaldehyde using an alkaline 4-amino-5-hydrazino-3-mercapto-1,2,4-triazole reagent is described. The method is particularly useful for determination of these aldehydes (0.5-50 nmol) when produced by the periodate oxidation of various glycols and can be applied to the assay of dilute solutions of sugars or polyols.
