Cas no 55873-09-1 (2-chloropyrimidin-4-ol)

2-Chloropyrimidin-4-ol is a heterocyclic compound featuring a chlorinated pyrimidine core with a hydroxyl substituent at the 4-position. This structure imparts reactivity suitable for nucleophilic substitution, making it a valuable intermediate in pharmaceutical and agrochemical synthesis. The chlorine atom at the 2-position enhances electrophilicity, facilitating cross-coupling reactions, while the hydroxyl group offers additional functionalization potential. Its stability under standard conditions and compatibility with diverse reaction conditions make it a versatile building block for constructing complex molecules. Applications include the development of active pharmaceutical ingredients (APIs) and specialty chemicals, where precise functional group manipulation is critical.
