4-Methoxyphenyl methyl sulfone is a versatile sulfone compound extensively used in pharmaceutical synthesis and material science. This crystalline solid exhibits a melting point of 120-121.5°C and boiling point of 341.1°C at 760 mmHg. With a density of 1.199 g/cm³ and refractive index of 1.511, it serves as a key intermediate for bioactive molecules and polymer precursors. The compound demonstrates excellent thermal stability and should be stored sealed in dry conditions at room temperature. Safety precautions include wearing protective equipment due to potential irritation to eyes/skin (GHS Category 2). Its methoxy and sulfone functional groups enable diverse chemical transformations, particularly in palladium-catalyzed coupling reactions.
