Description

12-Bromo-1,1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10-Heneicosafluorododecane is a highly fluorinated bromoalkane, serving as a critical building block in advanced organic synthesis. Its unique structure, featuring a long perfluoroalkyl chain terminated by a reactive bromine atom, makes it an indispensable intermediate for introducing fluorinated segments into target molecules. This compound is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and specialty materials sectors seeking to enhance product properties such as chemical resistance, thermal stability, and surface activity.

Application

• Pharmaceutical Intermediate: Used in the synthesis of fluorinated active pharmaceutical ingredients (APIs) to improve metabolic stability and membrane permeability.
• Agrochemical Synthesis: Serves as a key precursor for creating novel fluorinated pesticides and herbicides with enhanced efficacy and environmental profile.
• Fluorinated Surfactant & Polymer Production: Acts as a monomer or chain-transfer agent in the manufacture of high-performance fluoropolymers and specialty surfactants.
• Liquid Crystal & Electronic Material Development: Employed to synthesize fluorinated components for liquid crystal displays (LCDs) and dielectric fluids.
• Surface Modification Agent: Used to impart oleophobic and hydrophobic characteristics to textiles, coatings, and membranes.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new fluorination chemistry and material science.
