Tetrabromothiophene(CAS: 3958-03-0)

Tetrabromothiophene (CAS: 3958-03-0) is a crystalline compound with a molecular weight of approximately 273.08 g/mol. It is poorly soluble in water but soluble in common organic solvents like benzene, chloroform, and acetone. Chemically, it is highly reactive, particularly towards nucleophiles and reducing agents.

Tetrabromothiophene can be synthesized by reacting thiophene with bromine in the presence of a Lewis acid catalyst such as iron(III) bromide. The reaction is typically performed in a solvent like dichloromethane, leading to a fairly high yield of the product with good selectivity.

Tetrabromothiophene is used in various industries, including pharmaceuticals, where it can be a component in certain formulations, and in the production of polymers and semiconductors, where its unique electronic properties make it valuable for certain applications.

When handling tetrabromothiophene, wear appropriate personal protective equipment (PPE) including gloves, safety goggles, and a lab coat. Ensure the work is conducted in a fume hood due to its volatility. Keep the substance away from sources of heat and sparks. In case of a spill, immediately clean up using appropriate absorbents and follow the safety data sheet (SDS) guidelines for disposal.
