3. Intermediate in Organic Synthesis
Serves as a starting material for synthesizing various aromatic compounds, including:
Dyes
Agrochemicals
Pharmaceuticals
Useful in chlorinated aromatic compound research and halogen exchange reactions.
4. Research and Development
Employed in laboratories for polyaromatic compound studies.
Acts as a model compound in studies related to chlorinated hydrocarbons and environmental persistence.
Benefits
✅ High Chemical Stability: Resistant to heat and oxidation, making it suitable for some high-temperature applications.
✅ Good Solvency Power: Dissolves a variety of hydrophobic substances.
✅ Optical Uses: High refractive index makes it useful in microscopy and optics, particularly for RI matching in crystal and fiber studies.
