Description

Methyl4,4,5,5,6,6,6-Heptafluorohexanoate CAS NO 2070-60-2 is a high-purity fluorinated ester building block, valued for its unique combination of lipophilicity and chemical stability imparted by the heptafluoroalkyl chain. This compound is essential for introducing fluorine motifs into target molecules, significantly altering their physical and biological properties. It is primarily sought by R&D and production teams in the pharmaceutical, agrochemical, and advanced materials sectors for synthesizing novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key synthon for the development of fluorinated active pharmaceutical ingredients (APIs), where fluorine substitution can enhance metabolic stability, bioavailability, and membrane permeability.
• Agrochemical Synthesis: Used in creating advanced herbicides, fungicides, and insecticides, with the fluorinated moiety improving weatherfastness and biological activity.
• Fluorinated Polymer & Material Science: Serves as a monomer or modifier for producing specialty polymers with enhanced oil/water repellency, chemical resistance, and low surface energy for coatings and surface treatments.
• Liquid Crystal & Electronic Chemicals: Employed in the synthesis of fluorinated liquid crystals and dielectric fluids for high-performance display and electronic applications.
• Organic Synthesis & Catalysis: Acts as a versatile fluorinated building block in coupling reactions and as a precursor for other fluorinated carboxylic acids and derivatives in fine chemical synthesis.
