3-Deazauracil - Reference Information
| Introduction | 2, 4-dihydroxypyridine (Pyridine-2,4-diol) is a common intermediate in organic synthesis, the appearance was pale yellow powder at normal temperature and pressure. |
| Use | 2, 4-dihydroxypyridine as a common intermediate in organic synthesis, the main purpose is to use it as a molecular skeleton for structural modification and synthesis of drug molecules. The hydroxyl group on the molecular structure has a certain acidity, which can be easily made into alkyl ether to protect it, it provides a guarantee for the subsequent conversion of the amide bond. 2, 4-dihydroxypyridine may also be involved in the synthesis of nitrogen-containing heterocyclic ligands as a modified pyridine ring. |
