Description

1H,1H-2,5-Di(Trifluoromethyl)-3,6-Dioxaundecafluorononanol CAS NO 14548-74-4 is a high-value, highly fluorinated alcohol derivative, characterized by its unique perfluoropolyether (PFPE) segment and terminal hydroxyl group. This structure provides exceptional chemical and thermal stability, low surface energy, and hydrophobic/oleophobic properties, making it a critical intermediate for advanced material synthesis. It is primarily sought by R&D and manufacturing teams in the specialty chemical, electronics, and high-performance coatings industries for developing next-generation fluorinated surfactants, polymers, and surface modifiers.

Application

• Fluorinated Surfactant & Polymer Intermediate: Serves as a key building block for synthesizing novel fluorosurfactants and fluoropolymers with enhanced performance in demanding environments.
• Surface Modification Agent: Used to impart permanent water, oil, and stain repellency to textiles, paper, and advanced composite materials.
• Electronics Industry: Employed in the formulation of specialty coatings for electronic components and as a precursor for dielectric fluids or heat transfer fluids.
• Specialty Additives: Functions as a high-performance additive in lubricants, greases, and inks to reduce friction and improve surface wetting properties.
• Pharmaceutical & Agrochemical Intermediates: Utilized in the synthesis of bioactive molecules where the introduction of fluorine atoms can dramatically alter metabolic stability and bioavailability.
• Firefighting Foam Concentrates (Legacy/Reformulation R&D): Historically relevant as a precursor in fluorosurfactant blends for aqueous film-forming foams (AFFF); now critical for research into alternative formulations.

Quality Control

Every batch of 1H,1H-2,5-Di(Trifluoromethyl)-3,6-Dioxaundecafluorononanol is produced and analyzed under a strict quality management system. We ensure compliance with relevant industry standards and provide full traceability. Certificates of Analysis (COA) detailing purity, identity, and key physical properties are supplied with each shipment to guarantee consistency and meet your precise formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids and bases. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature is 2-8°C for long-term stability.
