Description

2-Bromo-3,3,4,4,4-Pentafluoro-1-Butene is a high-value fluorinated organic intermediate characterized by its unique combination of bromine and multiple fluorine atoms on a short-chain alkene. This molecular structure makes it a versatile and reactive building block for synthesizing more complex fluorinated compounds. It is primarily sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced materials sectors for introducing pentafluoroethyl and related functional groups.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs) containing fluorinated motifs, which can enhance metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in creating novel herbicides, insecticides, and fungicides where fluorine atoms improve efficacy and environmental persistence.
• Advanced Material Precursor: Serves as a monomer or modifier in the production of specialty polymers, coatings, and liquid crystals with unique thermal, chemical, or optical properties.
• Organic Synthesis Reagent: Employed in cross-coupling reactions and nucleophilic substitutions to introduce the 2-bromo-3,3,4,4,4-pentafluorobut-1-enyl moiety into target molecules.
• Fluorinated Surfactant & Lubricant Development: Acts as a starting material for synthesizing fluorosurfactants and high-performance lubricants with extreme stability.
