2-bromothiophene

2-Bromothiophene (CAS 1003-09-4), also known as 2-thienyl bromide, is a halogenated heterocyclic building block.

Where is 2-bromothiophene used?

• Pharmaceutical development: precursor for APIs with a thiophene core, including antifungal and antihistamine compounds
• Flavor and fragrance: access to thienyl-containing aroma compounds
• Suzuki, Kumada and Negishi coupling reactions for advanced intermediates
• Specialty chemicals: starting material for liquid crystal components and conducting polymer monomers
• It serves as a reactive intermediate for introducing the thiophene scaffold into complex organic molecules.

Good to know: Buyers should confirm grade documentation and certificate of analysis requirements; for GMP-regulated processes, ensure the material meets necessary quality standards. Proper handling and storage protocols must be followed.

Commercial specifications

• Purity typically 97–99%+
