Anthracene CAS #120-12-7
Chemical Stability: Anthracene is stable at high temperatures, with a melting point of 210-215°C and a boiling point of 340°C, making it suitable for various industrial applications.
Fluorescent Properties: The substance emits light blue fluorescence, which makes it valuable for certain optical and analytical applications.
Solubility and Handling: Although insoluble in water, anthracene dissolves easily in hot benzene and toluene, allowing it to be used in organic solvent-based processes.
Low Toxicity: Despite its hazardous classification, anthracene has low toxicity with an LD50 orally in rabbits greater than 16,000 mg/kg, making it relatively safe in controlled environments.
Anthracene is a polycyclic aromatic hydrocarbon composed of three fused rings, with the chemical formula C14H10. It is naturally found in coal tar. The three-ring structure of anthracene is aligned in a straight line, making it an isomer of phenanthrene.
The substance appears as a white flaky or light yellow needle-shaped crystal, emitting a light blue fluorescence. It has a melting point of 216°C, a boiling point of 340°C, and a relative density of 1.283 at 25/4°C. Anthracene readily sublimes and is insoluble in water, difficult to dissolve in ethanol and ether, but easily dissolves in hot benzene.
