Description

2,2,3,3,4,4-Hexafluoro-1,5-Pentanediol CAS NO 376-90-9 is a high-value fluorinated diol building block characterized by its unique perfluorinated carbon chain, which imparts exceptional chemical and thermal stability alongside hydrophobic and oleophobic properties. This compound is critical for synthesizing advanced materials where resistance to harsh environments, low surface energy, and specific dielectric properties are required. It is primarily sought after by R&D and production teams in the specialty polymers, advanced coatings, and pharmaceutical intermediates sectors.

Application

• Fluorinated Polymer Synthesis: A key monomer for producing high-performance polyurethanes, polyesters, and epoxy resins with enhanced chemical resistance, thermal stability, and low surface energy for non-stick and release coatings.
• Advanced Surface Modifiers & Coatings: Used to create hydrophobic and oleophobic surface treatments for textiles, optics, electronics, and architectural materials, providing stain, water, and oil repellency.
• Pharmaceutical & Agrochemical Intermediates: Serves as a versatile building block for introducing fluorinated motifs into active pharmaceutical ingredients (APIs) and agrochemicals, potentially improving bioavailability and metabolic stability.
• Specialty Additives: Incorporated into lubricants, greases, and functional fluids to enhance performance under extreme pressure and temperature conditions.
• Electronics & Semiconductor Materials: Utilized in the development of low-dielectric constant (low-k) materials for microelectronics and as a component in photoresists or other fluorinated electronic chemicals.
• Crosslinking Agent: Functions as a crosslinker in polymer networks to increase density, mechanical strength, and chemical inertness of the final cured material.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and potential degradation. Keep away from strong oxidizing agents.
