Description
Recommended products
Cis-12-Cyclohexanedicarboxylic Acid 98.0%(GC)
Application
It was first introduced as a method to detect reducing substances in urine and has since been widely used for example for quantifying carbohydrate levels in blood. It is mainly used in assay of alpha-amylase. However enzymatic methods are usually preferred due to DNS lack of specificity.
Purpose
For R&D use onlynot for drug household or other uses.
General Description
35-Dinitrosalicylic acid (DNS or DNSA IUPAC name 2-hydroxy-35-dinitrobenzoic acid) is an aromatic compound that reacts with reducing sugars and other reducing molecules to form 3-amino-5-nitrosalicylic acid which strongly absorbs light at 540 nm.
