Chemical Properties

white to slightly yellow crystalline powder or

Uses

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.

Definition

ChEBI: Uracil-5-carboxylic acid is a pyrimidinemonocarboxylic acid that is uracil carrying a carboxy group at position 5. It is functionally related to a uracil. It is a conjugate acid of a uracil-5-carboxylate. It is a tautomer of a 2,4-dihydroxypyrimidine-5-carboxylic acid.

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.
