Cas 4548-45-2 - Versatile Pyridine Intermediate

2-Chloro-5-nitropyridine (CAS 4548-45-2) is a highly reactive heteroaromatic compound widely used as an intermediate in pharmaceutical, agrochemical, and fine chemical synthesis. It contains both a chloro substituent and a nitro group on the pyridine ring, which allows for versatile chemical transformations. Chemical Characteristics This compound appears as a yellow to light brown crystalline solid. It is moderately soluble in organic solvents such as ethanol, acetone, and dichloromethane. The electron-withdrawing nitro group and the reactive chloro group make 2-chloro-5-nitropyridine suitable for nucleophilic substitution, reduction, and cross-coupling reactions. Applications Pharmaceutical Industry: Used as an intermediate in the synthesis of active pharmaceutical ingredients (APIs), especially for compounds targeting antibacterial, antiviral, and anticancer properties. Agrochemicals: Serves as a building block in the production of herbicides, fungicides, and other crop protection chemicals. Organic Synthesis: Utilized in the preparation of heterocyclic compounds, functionalized pyridines, and specialty chemicals. Its high reactivity enables efficient incorporation into larger molecular frameworks, making it a valuable reagent for medicinal chemistry and fine chemical research. Research and Industrial Value 2-Chloro-5-nitropyridine is prized for its stability under standard storage conditions and predictable reactivity, which ensures consistent results in laboratory and industrial-scale syntheses. It is suitable for method development, pilot-scale production, and large-scale manufacturing.
