4,4'-diisopropylbiphenyl; CAS No.: 18970-30-4; 4,4'-diisopropylbiphenyl. PROPERTIES: 4,4'-diisopropylbiphenyl appears as a colorless to pale yellow liquid with a slight aromatic odor. Its molecular formula is C18H20, corresponding to a molecular weight of approximately 236.35 g/mol. The compound exhibits a boiling point around 250-255 C at 760 mmHg and a density of about 0.95 g/cm? at 25 C. It demonstrates moderate solubility in common organic solvents such as toluene, hexane, and diethyl ether but is practically insoluble in water. The substance is stable under normal laboratory conditions but should be protected from prolonged exposure to heat and light. Proper storage involves keeping it in a tightly sealed container at room temperature (15-25 C) in a dry environment. Safety precautions include using chemical-resistant gloves, safety goggles, and lab coats to prevent skin absorption and inhalation of vapors. The compound may cause skin and eye irritation, and accidental ingestion may be harmful. In case of exposure, immediate rinsing with water and medical consultation is recommended. APPLICATIONS: 4,4'-diisopropylbiphenyl serves as a valuable intermediate in the synthesis of liquid crystal materials, where its biphenyl core and isopropyl substituents provide structural features important for mesomorphic properties and thermal stability (Liquid Crystals). In materials science, 4,4'-diisopropylbiphenyl functions as a building block for creating conjugated polymers and organic semiconductors used in organic photovoltaics and field-effect transistors. Its electron-rich biphenyl moiety enables effective charge transport properties, while the isopropyl groups enhance solubility and processability (Advanced Materials). Additionally, the compound finds application in the preparation of certain agrochemicals, though specific applications in this area are limited to non-agricultural research settings (Pest Management Science). It is also employed in the synthesis of certain pharmaceuticals, where its biphenyl structure provides opportunities for further functionalization and bioactive molecule design (Journal of Medicinal Chemistry).
