Description

Thiophene, 2-Bromo-3-Octadecyl- is a high-purity, long-chain substituted bromothiophene derivative, identified by CAS NO 827343-18-0. This specialty organic intermediate is valued for its unique molecular structure, which combines a reactive bromine atom with a hydrophobic octadecyl chain, making it a critical building block for advanced material synthesis. It is primarily sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced materials sectors for constructing complex molecules and functional polymers.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the development of novel active pharmaceutical ingredients (APIs), particularly for compounds requiring lipophilic side chains.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides, where the thiophene core contributes to biological activity.
• Organic Semiconductor Precursor: Acts as a monomer or building block in the synthesis of conjugated polymers and small molecules for organic field-effect transistors (OFETs) and photovoltaic cells.
• Liquid Crystal & Advanced Material Research: The long alkyl chain promotes self-assembly, making it useful in creating novel liquid crystalline materials and functional coatings.
• Chemical Research & Development: Employed in academic and industrial labs for methodology development, cross-coupling reactions (e.g., Suzuki, Stille), and exploring new material properties.
• Specialty Surfactant & Additive Synthesis: Utilized to create surface-active agents or polymer additives with specific hydrophobic characteristics.
