2-Chloro-5-nitropyridine

Description:

2-Chloro-5-nitropyridine is a heterocyclic organic compound characterized by a pyridine ring substituted with both a chlorine atom and a nitro group. The chlorine atom is located at the second position, while the nitro group is positioned at the fifth carbon of the pyridine ring. This compound typically appears as a yellow to brown solid and is known for its moderate solubility in organic solvents such as ethanol and acetone, but limited solubility in water. It has applications in the synthesis of pharmaceuticals, agrochemicals, and other fine chemicals due to its reactivity and ability to participate in various chemical reactions, including nucleophilic substitutions and coupling reactions. The presence of both electron-withdrawing groups (the nitro and chloro substituents) influences its chemical behavior, making it a valuable intermediate in organic synthesis. Safety precautions should be taken when handling this compound, as it may pose health risks, including potential toxicity and environmental hazards.
