Description

1,1-Bis(4-Fluorophenyl)-1-Butene CAS NO 128104-20-1 is a specialized fluorinated organic compound featuring a butene core flanked by two 4-fluorophenyl groups. This unique structure makes it a valuable advanced intermediate for the synthesis of complex molecules in pharmaceutical and agrochemical research. It is primarily sought after by R&D chemists and process development scientists working on novel active ingredients, particularly in the areas of medicinal chemistry and crop protection.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of potential drug candidates, especially those targeting central nervous system (CNS) disorders or possessing specific receptor-binding profiles.
• Agrochemical Research: Serves as a precursor in the development of new herbicides, fungicides, or insecticides, leveraging the bioactivity often imparted by fluorinated aromatic systems.
• Material Science Precursor: Used in the research and development of specialty polymers, liquid crystals, or organic electronic materials where fluorinated aromatic units enhance stability and performance.
• Organic Synthesis Reagent: Employed in cross-coupling reactions, such as Suzuki or Heck reactions, to introduce fluorinated biphenyl motifs into more complex molecular architectures.
• Chemical Reference Standard: Utilized as a high-purity analytical standard for method development and quality control in laboratories analyzing fluorinated compounds.
