2,2'-Biquinoline(CAS: 119-91-5)

2,2'-Biquinoline is a yellow crystalline solid with a molecular weight of approximately 232.2 g/mol. It has a relatively low solubility in water but is soluble in common organic solvents like ethanol and methanol. Chemically, it is known for its good electron donor properties, making it useful in various redox reactions. It is also slightly basic due to its quinoline rings.

2,2'-Biquinoline is commonly synthesized by the condensation of 2,4-dinitroquinoline with 2,4-dinitrobenzaldehyde. This reaction is catalyzed by sodium hydroxide and typically yields 2,2'-biquinoline in a moderate to good yield. The process is controlled to achieve high selectivity and reproducibility.

2,2'-Biquinoline finds applications in various industries. It is used in the pharmaceutical sector for its antioxidant and anticancer properties. In the polymer industry, it serves as a precursor for the synthesis of conducting polymers. Additionally, it is utilized in the production of chemical sensors and semiconductors due to its unique electronic properties.

When handling 2,2'-Biquinoline, it is important to use appropriate personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat. It should be stored in a well-ventilated area and away from strong oxidizing agents. In case of a spill, use appropriate spill cleanup procedures and ensure the area is properly ventilated. Always refer to the Safety Data Sheet (SDS) for detailed handling and storage information.
