Introduction
1. Physicochemical Properties
- Structure: A biphenyl framework with a heptyl group at the 4-position of one phenyl ring and a nitrile group at the 4′-position of the other phenyl ring.
- Molecular Formula: C₂₀H₂₃N
- Molecular Weight: 277.41 g/mol
- Physical Characteristics:
- Appearance: Solid
- Melting Point: 30-32°C
- Boiling Point: High (exact value not provided)
- Flash Point: >230°F
2. Synthesis Method
The compound is likely synthesized via substitution reactions, involving the introduction of a heptyl group and a nitrile group onto the biphenyl core. Specific methods may include:
- Alkylation of biphenyl to introduce the heptyl group.
- Cyanation of the alkylated biphenyl to introduce the nitrile group.
- Purification: Chromatography or recrystallization to isolate the desired product.
3. Applications
- Liquid Crystals: The rigid biphenyl structure and long alkyl chain make it a candidate for liquid crystal materials, where it could influence molecular alignment and optical properties.
- Pharmaceutical Synthesis: The nitrile group may serve as a reactive handle for further functionalization, making it a useful intermediate in drug synthesis.
4. Safety Information
- Handling: Follow standard chemical safety protocols (e.g., use gloves, goggles, and fume hoods). Avoid skin contact and inhalation.
- Storage: Keep in a cool, dry place, away from oxidants and strong acids.
- Disposal: Consult local regulations for hazardous waste disposal.
Hazard Information:
- GHS Classification: Harmful (Xn)
