[0002] Pyrimidine is a six-membered heterocyclic compound containing two nitrogen atoms, which has unsaturation and aromaticity. Dihydroxy pyrimidine is connected with two hydroxyl groups at different carbon atom positions of the pyrimidine ring. Common dihydroxy pyrimidines include 2,4-dihydroxy pyrimidine, 2,5-dihydroxy pyrimidine, 2,6-dihydroxy pyrimidine and the like. Hydroxyl substitution at different positions will make the compounds have different chemical properties and uses. Generally, dihydroxy pyrimidines are white or white-like crystalline powders, and have relatively high melting points and boiling points, and are stable at normal temperature and pressure. The solubility in different solvents is different, for example, they have certain solubility in polar solvents such as water and ethanol, but the specific solubility is affected by factors such as temperature and solvent polarity.
