5-Bromo-1-benzothiophene(CAS: 4923-87-9)

5-Bromo-1-benzothiophene is a solid with a crystalline form. Its molecular weight is approximately 213.03 g/mol. It is slightly soluble in common organic solvents. Reactively, it is stable under standard conditions but can undergo electrophilic aromatic substitution reactions. It is also prone to photodegradation.

5-Bromo-1-benzothiophene is usually synthesized via bromination of 1-benzothiophene using bromine in the presence of a Lewis acid catalyst such as aluminum tribromide. The reaction typically yields a pure product with good selectivity and moderate to high yield.

5-Bromo-1-benzothiophene is used in the pharmaceutical industry for the synthesis of bioactive compounds and in semiconductor industry for the production of electronics materials. It is also relevant in polymer and sensor applications due to its aromatic and thienyl characteristics.

When handling 5-Bromo-1-benzothiophene, it is important to wear appropriate personal protective equipment (PPE) such as gloves and safety goggles. Store it in a well-ventilated area, away from direct sunlight and heat sources. In case of spill, immediately contain and clean up using appropriate absorbents, and consult the Material Safety Data Sheet (MSDS) for further instructions.
