1,3-Dichloro-5-fluoro-2-nitrobenzene(CAS: 180134-21-8)

1,3-Dichloro-5-fluoro-2-nitrobenzene is a dark yellow crystalline solid with a molecular weight of approximately 262.03 g/mol. It has low solubility in water but is more soluble in organic solvents like ethanol and acetone. Chemically, it is highly reactive due to the presence of the nitro group and chlorine atoms, making it prone to substitution reactions and oxidation.

1,3-Dichloro-5-fluoro-2-nitrobenzene can be synthesized via nitration and chlorination of 5-fluoro-2-nitrobenzene. The reaction involves the gradual addition of chlorine in the presence of a Lewis acid catalyst, followed by nitration using nitric acid in the presence of sulfuric acid. Reaction conditions and catalysts can influence the yield and selectivity of the product.

1,3-Dichloro-5-fluoro-2-nitrobenzene finds applications in the pharmaceutical industry for the synthesis of certain medicinal compounds. It is also used in the production of dyes and pigments, as well as in the development of sensors and materials for the semiconductor industry. Its unique chemical properties make it a valuable intermediate in various chemical processes.

When handling 1,3-Dichloro-5-fluoro-2-nitrobenzene, ensure the use of appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work in a well-ventilated area or a fume hood to minimize inhalation of vapors. Dispose of any spills or waste according to local regulations and refer to the safety data sheet (SDS) for detailed procedures. This compound is highly reactive and can pose health risks if not handled properly.
