2-Fluoro-3-methylaniline(CAS: 1978-33-2)

2-Fluoro-3-methylaniline (CAS: 1978-33-2) is a crystalline solid with a molecular weight of approximately 140.04 g/mol. It is slightly soluble in water and more soluble in organic solvents like ethanol and acetone. It has a melting point of 55-57°C and is reactive towards nucleophiles and electrophiles. It can undergo electrophilic aromatic substitution reactions and nucleophilic substitution at the methyl group.

2-Fluoro-3-methylaniline (CAS: 1978-33-2) is typically synthesized by the reaction of 3-methylaniline with hydrofluoric acid or by the alkylation of 2-fluoroaniline with methyl iodide in the presence of a catalyst such as sodium hydride. The reaction yields a mixture that requires purification techniques such as recrystallization and chromatography to obtain the pure compound.

2-Fluoro-3-methylaniline (CAS: 1978-33-2) is used in the pharmaceutical industry for the synthesis of certain drugs, in the polymer industry for the production of functionalized polymers, and in the chemical sensors industry for the development of sensor materials. It also finds applications in the semiconductor industry as an intermediate in the production of certain organic semiconductors.

When handling 2-Fluoro-3-methylaniline (CAS: 1978-33-2), appropriate personal protective equipment (PPE) should be used, including gloves, goggles, and a lab coat. The compound should be handled in a fume hood to minimize exposure to vapors. In case of a spill, it should be cleaned up using appropriate absorbents and the area should be well-ventilated. Always refer to the Safety Data Sheet (SDS) for detailed safety information and emergency procedures.
