4-Methoxypyridine is an important pyridine derivative intermediate widely used in pharmaceutical and fine chemical industry. The methoxy group endows fine reactivity to support substitution, condensation and coupling reactions. It acts as fundamental building block for synthesizing anti-inflammatory, antibacterial and neurological therapeutic drugs, enhancing molecular stability and pharmacological activity. It is also applied to produce agrochemical pesticides and plant growth regulators. Besides, it serves as organic base catalyst, analytical reagent and material modifier. Its favorable chemical property makes it widely used in new drug research, pesticide development and organic synthesis manufacturing.
