1-Bromo-2,3,5-trifluorobenzene(CAS: 133739-70-5)

1-Bromo-2,3,5-trifluorobenzene (CAS: 133739-70-5) is a crystalline solid with a molecular weight of approximately 252.01 g/mol. It is sparingly soluble in water but soluble in common organic solvents like ethanol, acetone, and dichloromethane. The compound is less reactive than other brominated benzenes due to the electron-withdrawing fluorine substituents, which decrease its electrophilicity. It is stable under normal storage conditions and is often used in organic synthesis and as a precursor in various industries.

1-Bromo-2,3,5-trifluorobenzene (CAS: 133739-70-5) can be synthesized via a series of reactions, starting with bromination of 2,3,5-trifluorobenzenediol followed by bromination of the phenolic hydroxyl group. Common methods include the use of bromine in the presence of a base or a phase-transfer catalyst, which enhances selectivity. The reaction is typically conducted under anhydrous conditions to avoid side reactions. High yield and selectivity can be achieved with proper conditions.

1-Bromo-2,3,5-trifluorobenzene (CAS: 133739-70-5) finds applications in various industries, including pharmaceuticals, where it serves as an intermediate for synthesizing drug molecules, and as a precursor in the production of advanced polymers with enhanced thermal stability. It is also used in the development of chemical sensors and semiconductor materials due to its unique electronic properties.

When handling 1-Bromo-2,3,5-trifluorobenzene (CAS: 133739-70-5), it is essential to use appropriate personal protective equipment (PPE), including safety goggles, gloves, and lab coats.
