2-Fluorophenethyl bromide(CAS: 91319-54-9)

2-Fluorophenethyl bromide is a colorless or white crystalline solid with a molecular weight of approximately 217.03 g/mol. It has a low solubility in water but is more soluble in organic solvents like ethanol and chloroform. This compound is moderately reactive, especially in the presence of nucleophiles. It is typically used in organic synthesis as a fluorinated aromatic intermediate.

2-Fluorophenethyl bromide is synthesized via the reaction of 2-phenylethanol with phosphorus tribromide in the presence of a catalytic amount of triethylamine. The reaction is carried out at room temperature and provides good selectivity and yield, making it a common method for preparing this compound.

2-Fluorophenethyl bromide is primarily used in the pharmaceutical and polymer industries. It serves as a key intermediate for the synthesis of various fluorinated compounds, which are used in drug development and as monomers for fluoroelastomers and other advanced polymers. It also finds applications in the development of sensors and semiconductors.

When handling 2-Fluorophenethyl bromide, it is essential to use 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 to minimize exposure. Spills should be carefully cleaned up using appropriate absorbent materials, and the area should be well flushed with water. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
