Description

(E)-1,1,1-Trifluoro-4-(2-(Trifluoromethyl)-5,6-Dihydrocyclopenta[B]Pyran-7-Yl)But-3-En-2-One is a high-value, fluorinated organic intermediate characterized by its unique dihydrocyclopentapyran scaffold and multiple trifluoromethyl groups. This compound matters for its role as a critical building block in advanced synthetic chemistry, enabling the introduction of lipophilicity and metabolic stability into target molecules. It is primarily needed by research and development teams in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders and inflammatory diseases.
• Agrochemical Research: Used in the development of next-generation herbicides and pesticides, where the fluorine atoms enhance biological activity and environmental persistence.
• Material Science: Acts as a monomer or cross-linking agent for creating specialty polymers with unique optical or surface properties.
• Liquid Crystal & OLED Development: The rigid, fluorinated structure makes it suitable for research into advanced electronic display materials.
• Chemical Synthesis: Employed in organic methodology research as a model substrate for novel fluorination or cross-coupling reactions.
