General description

2,4-Dihydroxypyrimidine-5-carboxylic acid (Uracil-5-carboxylic acid) has been obtained from 5-formyluracil by the action of enzyme, thymine 7-hydroxylase. It has been used to synthesize N1-alkylated uracil derivatives.

Application

2,4-Dihydroxypyrimidine-5-carboxylic acid (Uracil-5-carboxylic acid) has been used for the visual sensing of melamine (at parts-per-billion (ppb) level) by a highly sensitive analytical method based on Au nanoparticles.
