4-Methylsulfonylphenol (4-Hydroxyphenyl methyl sulfone) is a key sulfone derivative widely used in pharmaceutical synthesis and material science. This compound exhibits a melting point of 156-158°C (lit.) and predicted boiling point of 372.5±27.0°C at 760 mmHg. With a density of 1.369±0.06 g/cm³ and pKa of 7.83 (25°C), it serves as a versatile intermediate for bioactive molecules and polymer modifiers. The material should be stored in sealed containers at room temperature, protected from light and moisture. Safety precautions include wearing protective gloves/eyewear due to potential skin/eye irritation (GHS Category 2). Its unique sulfone-phenol structure enables applications in asymmetric synthesis and specialty material development.
