Description

Benzenemethanol, 2-Ethynyl-5-Fluoro- (9Ci) is a specialized fluorinated aromatic building block featuring both a propargyl alcohol and a fluorine substituent on the benzene ring. This unique molecular architecture makes it a high-value intermediate for the synthesis of complex molecules in advanced research and development. It is primarily sought after by pharmaceutical and agrochemical R&D teams for constructing novel active ingredients and by material scientists exploring new functional polymers.

Application

• Pharmaceutical Intermediate: A key synthon for the development of fluorinated drug candidates, particularly in oncology and central nervous system (CNS) therapeutic areas.
• Agrochemical Synthesis: Used in the research and production of advanced, fluorinated pesticides and herbicides to enhance biological activity and environmental stability.
• Material Science Research: Serves as a monomer or cross-linking agent in the development of specialty polymers, resins, and advanced organic electronic materials.
• Chemical Biology & Proteomics: Employed as a click chemistry handle (via the alkyne group) for bioconjugation, labeling, and probe development in life science research.
• Liquid Crystal & OLED Materials: Acts as a fluorinated core component in the synthesis of materials for display and lighting technologies.
