Description and Uses

3,5-Dinitrosalicylic acid is used in the quantification of reducing sugars by colorimetry. It is utilized for the analysis of glycosidase (glycoside hydrolase) activity by quantitation of enzymatically released reducing sugar. It is also used to detect reducing substances in urine and for quantifying carbohydrate level in blood. It acts as an important raw material and an intermediate in the production of organic chemicals such as agrochemicals, organic synthesis, pharmaceuticals and dyes.
