Description

3,3,4,4,5,5,6,6,7,7,7-Undecafluoro-2-Heptanol is a high-value fluorinated alcohol intermediate characterized by its unique perfluorinated alkyl chain. This compound matters for its ability to impart exceptional hydrophobicity, oleophobicity, and chemical resistance when incorporated into polymers and surface treatments. It is primarily needed by manufacturers in the specialty chemical, advanced materials, and pharmaceutical sectors for developing high-performance products.

Application

• Key intermediate in the synthesis of fluorinated surfactants and emulsifiers.
• Building block for high-performance fluorinated polymers and resins.
• Surface modification agent to create water- and oil-repellent coatings for textiles and electronics.
• Precursor for pharmaceutical intermediates requiring fluorinated motifs to modulate bioavailability and metabolic stability.
• Raw material for producing specialized fluorinated plasticizers and additives.
• Used in the formulation of advanced fire-fighting foams (where regulations permit).
• Component in the development of anti-reflective and anti-fogging coatings for optical applications.
