Description

1,1'-[Oxybis[(1-Methylethylene)Oxy]]Bis[4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,14,15,15,15-Pentacosafluoropentadecan-2-Ol] is a high-purity, specialized fluorinated polyether diol intermediate. This compound matters for its unique combination of extreme hydrophobicity, oleophobicity, and chemical inertness imparted by its long perfluorinated chains, which are linked by a flexible polyether spacer. It is critically needed by R&D and production teams in advanced material science for synthesizing next-generation surface modifiers, high-performance lubricants, and specialty polymers. The CAS number for this product is 93776-00-2.

Application

• Surface Modification Agent: Key intermediate for synthesizing fluorosurfactants and coatings that provide exceptional water, oil, and stain repellency to textiles, membranes, and electronic components.
• Polymer Synthesis: Serves as a fluorinated monomer or chain extender for creating specialty polyurethanes, polyesters, and epoxy resins with enhanced chemical resistance and low surface energy.
• Lubricant & Release Agent Formulation: Used in the development of high-performance fluorinated lubricants, greases, and mold release agents for demanding industrial and aerospace applications.
• Firefighting Foam Concentrates (Legacy/Reformulation): Historically used as a precursor in certain fluorosurfactant blends for aqueous film-forming foams (AFFF); current applications focus on research for environmentally responsible alternatives.
• Pharmaceutical & Agrochemical Intermediates: Employed in the synthesis of fluorinated active pharmaceutical ingredients (APIs) and agrochemicals to alter bioavailability and metabolic stability.
• Electronic Materials: Incorporated into dielectric fluids, heat transfer liquids, and protective coatings for sensitive electronic equipment due to its thermal stability and insulating properties.

Quality Control

Every batch of our fluorinated intermediates is produced under strict quality management protocols. We employ advanced analytical techniques including NMR (¹⁹F and ¹H), HPLC, and FTIR to ensure structural identity, purity, and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment. Our quality system is designed to support cGMP and ISO 9001 standards for traceability and reliability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Keep away from strong alkalis and incompatible materials. Due to the chemical nature of fluorides, ensure containers are properly sealed to prevent moisture ingress and are clearly labeled.
