Description

Benzene, 1-Fluoro-4-(1-Methyl-3-Butenyl)- (9Ci) is a specialized fluorinated benzene derivative featuring an alkenyl side chain, making it a valuable building block in advanced organic synthesis. This compound matters for its role as a key intermediate in the development of pharmaceuticals, agrochemicals, and functional materials, where its unique structure enables precise molecular modifications. It is needed by research and development chemists, process scale-up teams, and manufacturers in the fine chemical and life science industries seeking to introduce specific fluorinated motifs into complex molecules.

Application

• Pharmaceutical Intermediate: Serves as a crucial precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring fluorinated aromatic systems for enhanced metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and pesticides, where the fluorine atom and olefinic handle can improve target activity and environmental profile.
• Liquid Crystal & OLED Material Research: Acts as a building block for fluorinated components in electronic display materials and organic light-emitting diodes (OLEDs), contributing to desired electronic and physical properties.
• Polymer & Specialty Chemical Modifier: Employed to introduce fluorinated phenyl groups into polymers or specialty chemicals to alter characteristics like solubility, thermal stability, or surface energy.
• Cross-Coupling Reactions: The alkenyl side chain makes it a suitable substrate or partner in various metal-catalyzed cross-coupling reactions (e.g., Heck, Suzuki) for constructing complex molecular architectures.
• Academic & Contract Research: Utilized in university and CRO (Contract Research Organization) laboratories for methodological development and exploring new chemical spaces in fluoroorganic chemistry.
