3,5-dinitrosalicylic acid (DNSA) reacts with sugars to form 3-amino-5-nitrosalicylic acid. This is an important reaction because the product (3-amino-5-nitrosalicylic acid) absorbs light at a very specific wavelength (540 nm) which allows for a very accurate quantification of the amount of sugar reacted. For this reason it is used in many medical and forensic testing.
