Description

4,4,5,5,6,6,6-Heptafluorohexane-1,2-Diol is a high-purity fluorinated diol building block, distinguished by its unique perfluoroalkyl chain. This compound matters for its ability to impart exceptional hydrophobicity, oleophobicity, and chemical resistance to advanced materials. It is primarily needed by R&D chemists and formulators in the pharmaceutical, agrochemical, and specialty polymer industries for synthesizing novel surfactants, coatings, and bioactive molecules.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing novel fluorinated active pharmaceutical ingredients (APIs) and prodrugs, enhancing metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the development of next-generation fluorinated pesticides and herbicides, where the fluorine atoms improve efficacy and environmental persistence profiles.
• Specialty Polymer & Resin Modifier: Incorporated into polyurethanes, polyesters, and epoxy resins to create surfaces with superior water and oil repellency (stain resistance).
• Fluorinated Surfactant & Emulsifier: Serves as a critical precursor for high-performance surfactants used in demanding applications like fire-fighting foams and electronics coatings.
• Surface Treatment & Coating Formulations: Enhances the performance of coatings for textiles, electronics, and optical devices by providing low surface energy.
• Material Science Research: A valuable reagent for academic and industrial research into new fluorinated materials with tailored properties.

Quality Control

Our 4,4,5,5,6,6,6-Heptafluorohexane-1,2-Diol is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure compliance with exacting customer specifications. Comprehensive Certificates of Analysis (COA) documenting identity, assay, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under a dry, inert atmosphere (e.g., nitrogen) in a cool, dry place at room temperature (15-25°C). Keep away from strong oxidizing agents.
