QUINOLINE-4-ALDEHYDE - Introduction
4-Quinolinecarboxaldehyde is an organic compound with the chemical formula C10H7NO. It is a yellow to orange-red crystalline solid.
Nature:
-Melting point: 60-62°C
-Boiling Point: 345-347°C
-Density: 1.21g/cm³
-Solubility: Almost insoluble in water, but soluble in organic solvents such as ethanol and chloroform.
Use:
4-Quinolinecarboxaldehyde has certain biological activity, so it is often used in drug synthesis and biological research. It can be used as an intermediate for dyes, pigments and high-performance coatings. In addition, it can also be used for the synthesis of fungicides, disinfectants and heterocyclic compounds.
Preparation Method:
4-Quinolinecarboxaldehyde can be obtained by oxidation of quinoline. A common method is to react quinoline with cyanogen chloride to obtain tetraphenylphosphine chloride (PClPh4), which is then reacted with aluminum trichloride (AlCl3) to form the corresponding tetraphenylphosphine aluminum trichloride salt ((PClPh4)AlCl3). Finally, the tetraphenylphosphine trichloride aluminum salt is hydrolyzed to give 4-Quinolinecarboxaldehyde.
Safety Information:
4-Quinolinecarboxaldehyde is an organic compound with certain toxicity and irritation. When in use should comply with the relevant safety procedures, such as wearing protective gloves and glasses, and ensure that the operation under good ventilation conditions. Avoid contact with skin, eyes and respiratory tract. If ingested or inhaled, seek medical attention immediately. When carrying and storing, care should be taken to avoid contact with oxidants and strong acids.
