Description

1-Bromo-1,1,2,2,3,3,4,4-Octafluorobutane is a high-purity, fully halogenated alkane derivative, serving as a critical building block and intermediate in advanced chemical synthesis. Its unique structure, featuring a terminal bromine atom on a perfluorinated butyl chain, makes it an invaluable reagent for introducing fluorinated segments with a reactive handle. This compound is essential for manufacturers and R&D laboratories in the pharmaceutical, agrochemical, and specialty materials sectors seeking to enhance product properties through fluorination.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and diagnostic agents where fluorination improves metabolic stability and bioavailability.
• Agrochemical Synthesis: Serves as a key precursor for developing novel herbicides, pesticides, and fungicides with enhanced efficacy and environmental persistence.
• Fluorinated Polymer & Material Science: Acts as a monomer or modifier in the production of specialty fluoropolymers, surfactants, and coatings that require oil, water, and chemical resistance.
• Organic Synthesis Reagent: Employed in nucleophilic substitution and coupling reactions to incorporate perfluorobutyl groups into complex organic molecules.
• Electronics & Semiconductor Industry: Used in plasma etching processes and as a precursor for depositing fluorinated carbon films.
• Refrigerant & Propellant Research: Investigated as a component in next-generation, low-global-warming-potential (GWP) refrigerant blends and aerosol propellants.
