Basic Information

Structural Information

• Structure Type: Aromatic phenolic compound, biphenyl derivative
• Structural Features: Consists of two connected benzene rings with a hydroxyl group on the 4-position. The phenolic hydroxyl group endows it with typical reactivity of phenols.

Physical & Chemical Properties

• Appearance: White to off-white crystalline powder
• Odor: Slight characteristic odor
• Melting Point: 164–166 °C
• Boiling Point: 305 °C
• Density: 1.21 g/cm3 (20 °C)
• Solubility: Insoluble in water; soluble in ethanol, ether, acetone, toluene and hot organic solvents
• Stability: Stable under normal sealed conditions. Gradually oxidizes and darkens under long exposure to light and air. Reacts with strong bases and strong oxidants.
