4-Chloro-2-nitropyridine(CAS: 65370-42-5)

4-Chloro-2-nitropyridine is a crystalline solid with a molecular weight of approximately 177.58 g/mol. It is slightly soluble in water but readily soluble in organic solvents such as ethanol and acetone. Chemically, it exhibits basic properties due to the nitro group and is prone to hydrolysis under basic conditions. It is also reactive towards nucleophiles and can undergo substitution reactions.

4-Chloro-2-nitropyridine is typically synthesized via the nitration of 4-chloropyridine. This process involves the use of nitric acid and sulfuric acid as the nitrating agent. The yield can vary depending on the reaction conditions, but the process is generally straightforward and can achieve high selectivity and yield under optimal conditions.

4-Chloro-2-nitropyridine is primarily used in the pharmaceutical industry for the synthesis of various drug intermediates. It is also utilized in the polymer industry for the development of new materials and in the sensor industry for its sensitivity to certain chemical species. Additionally, it has applications in the semiconductor industry for its use in thin film deposition processes.

Proper handling of 4-Chloro-2-nitropyridine requires the use of personal protective equipment (PPE) such as gloves, goggles, and a lab coat. It should be handled in a well-ventilated area or a fume hood to minimize exposure to vapors. Spills should be cleaned up using appropriate materials, and the area should be well-ventilated. Always refer to the Safety Data Sheet (SDS) for detailed safety information and emergency procedures.
