3,5-Dinitrosalicylic acid (DNS) is a nitro-substituted derivative of salicylic acid commonly used as a colorimetric reagent for the quantitative determination of reducing sugars. When heated with a sugar solution under alkaline conditions, DNS is reduced to 3-amino-5-nitrosalicylic acid, forming a reddish-brown complex measurable by UV-Vis spectrophotometry.
With a purity of ≥98% and titration value of ≥97.5%, this yellow crystalline powder is ideal for use in enzyme assays, biochemical studies, and analytical chemistry protocols, particularly in carbohydrate quantification and food chemistry.
