Cas no 72141-44-7 (4-Chloro-2-methoxypyridine)
4-Chloro-2-methoxypyridine is a versatile heterocyclic compound featuring a chloro substituent at the 4-position and a methoxy group at the 2-position of the pyridine ring. This structure imparts reactivity suitable for various synthetic applications, particularly in pharmaceutical and agrochemical intermediates. The electron-withdrawing chloro group enhances electrophilic substitution potential, while the methoxy group contributes to stability and influences regioselectivity in further functionalization. Its high purity and well-defined reactivity profile make it a valuable building block for cross-coupling reactions, nucleophilic substitutions, and other transformations. The compound is typically handled under standard laboratory conditions, with appropriate precautions for halogenated pyridines.
