Description

2H,2H,3H,3H-Perfluorodecanoic Acid CAS NO 812-70-4 is a partially fluorinated carboxylic acid characterized by its unique combination of a perfluorinated carbon chain tail and a hydrogenated carboxylic acid head group. This structure provides distinct surface-active properties and chemical stability, making it a valuable intermediate for advanced material synthesis. It is primarily sought by R&D and production teams in the specialty chemical, polymer, and surface coating industries for developing high-performance fluorinated compounds.

Application

• Fluorinated Surfactant & Polymer Intermediate: Serves as a key building block for synthesizing specialty fluorosurfactants and fluoropolymers with enhanced oil, water, and chemical resistance.
• Surface Modification Agent: Used to impart low surface energy and hydrophobic/oleophobic properties to textiles, papers, and various substrates.
• Lithography & Electronics: Acts as a photoresist additive or component in formulations for advanced semiconductor manufacturing processes.
• Firefighting Foams (Legacy/Formulation R&D): Historically used as a precursor in the synthesis of fluorosurfactants for aqueous film-forming foams (AFFF); relevant for research into alternative formulations.
• Catalyst & Ligand Synthesis: Utilized in the preparation of metal-organic catalysts and ligands for specialized organic reactions.
• Analytical Chemistry & Research: Employed as a standard or reagent in analytical methods and academic research exploring fluorocarbon chemistry.
