4-Chloro-3-(2-pyridinyl)aniline(CAS: 879088-41-2)

4-Chloro-3-(2-pyridinyl)aniline is a crystalline compound with a molecular weight of approximately 227.58 g/mol. It has a low solubility in water but is more soluble in organic solvents like ethanol and acetone. The compound exhibits basic properties due to its amine group and can react with acids to form salts. It is moderately stable but can undergo photodegradation under strong light conditions.

4-Chloro-3-(2-pyridinyl)aniline is typically synthesized via a multistep process involving the reaction of 2-chloropyridine with aniline. This reaction is catalyzed by a Lewis acid such as aluminum chloride, leading to good yield and selectivity. The process requires careful temperature control and may involve the use of solvents like dichloromethane.

4-Chloro-3-(2-pyridinyl)aniline is used in various industries, including pharmaceuticals, where it serves as an intermediate in the synthesis of certain drugs. It is also utilized in the production of dyes and pigments, and in some cases, as a precursor for the development of sensors and electronic materials.

Proper handling of 4-Chloro-3-(2-pyridinyl)aniline requires the use of personal protective equipment (PPE) such as gloves, safety goggles, and lab coats. Work should be conducted in a well-ventilated area or a fume hood. Spills should be immediately contained and managed according to the Material Safety Data Sheet (MSDS). Always follow laboratory safety protocols and ensure proper storage in a cool, dry place away from direct sunlight.
