2,3-Difluoroaniline(CAS: 4519-40-8)

2,3-Difluoroaniline is a colorless or white crystalline solid with a molecular weight of approximately 154.01 g/mol. It is slightly soluble in water but soluble in organic solvents like ethanol and acetone. Chemically, it reacts with bases to form anilinium salts and is used in making dyes and pharmaceuticals. It is also used in the synthesis of herbicides and flame retardants.

2,3-Difluoroaniline is typically synthesized via the reduction of 2,3-difluorophenyl isocyanate or by the reaction of 2,3-difluorophenyl methyl ketone with ammonia. The reaction conditions include the use of a suitable reducing agent and a catalyst, which can enhance the yield and selectivity of the product.

2,3-Difluoroaniline is used in various industries, including pharmaceuticals, where it serves as a precursor to medications; in the synthesis of herbicides; and in the production of dyes and other organic compounds. It also finds applications in the manufacturing of flame retardants and as a reagent in semiconductor and sensor technologies.

When handling 2,3-Difluoroaniline, it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood. Spills should be cleaned up using appropriate chemical waste disposal methods, and the Material Safety Data Sheet (MSDS) should be consulted for detailed safety information.
