Description

3,3,4,4,5,5,5-Heptafluoro-2-pentanol is a high-value fluorinated alcohol characterized by its unique combination of a hydroxyl group and a perfluorinated alkyl chain. This structure provides exceptional properties, including high thermal and chemical stability, low surface energy, and significant hydrophobicity, making it a critical intermediate for advanced materials. It is primarily sought after by R&D and production teams in the pharmaceutical, agrochemical, and specialty polymer industries for synthesizing novel compounds with enhanced performance characteristics.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring fluorinated moieties to improve metabolic stability, bioavailability, and membrane permeability.
• Agrochemical Synthesis: Serves as a key building block for creating advanced herbicides, fungicides, and insecticides where fluorine incorporation enhances efficacy and environmental persistence.
• Fluorinated Surfactants & Polymers: Acts as a monomer or modifier in the production of specialty polymers, coatings, and surfactants that demand oil- and water-repellency, and low surface tension.
• Electronics & Semiconductor Industry: Employed in the formulation of specialty cleaning agents, etching solutions, and as a precursor for materials used in lithography and thin-film deposition.
• Liquid Crystal & Display Materials: Utilized in the development of fluorinated liquid crystals and optical materials for high-performance displays.
• Research & Development: A valuable reagent in organic synthesis and medicinal chemistry for introducing heptafluoropentyl groups to explore new chemical spaces.

Quality Control

Our 3,3,4,4,5,5,5-Heptafluoro-2-pentanol is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistency suitable for demanding synthetic applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

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 to prevent absorption of atmospheric moisture. Keep away from strong acids, strong bases, and oxidizing agents.
