Description

4,4,5,5,6,6,7,7,7-Nonafluoroheptane-1,2-Diol is a high-value, fluorinated diol intermediate characterized by its unique combination of a hydrophobic perfluoroalkyl chain and hydrophilic hydroxyl groups. This bifunctional structure makes it a critical building block for synthesizing advanced materials with tailored surface properties, including exceptional oil and water repellency. It is primarily sought after by R&D and production teams in the specialty chemical, polymer, and surface coating industries for developing next-generation fluorosurfactants, additives, and high-performance polymers.

Application

• Fluorosurfactant & Polymer Intermediate: A key monomer for synthesizing novel fluorinated polyurethanes, polyesters, and acrylics, imparting oil, water, and stain resistance.
• Surface Modifier & Coating Additive: Used to create low surface energy coatings for textiles, electronics, and optical devices, enhancing durability and performance.
• Pharmaceutical & Agrochemical Intermediate: Serves as a building block for introducing fluorinated motifs into bioactive molecules, potentially altering their metabolic stability and lipophilicity.
• Specialty Material Synthesis: Employed in the research and development of fluorinated gels, resins, and elastomers for demanding industrial applications.

Quality Control

Our 4,4,5,5,6,6,7,7,7-Nonafluoroheptane-1,2-Diol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong bases and sources of ignition. Due to its sensitivity to light and potential reactivity with strong alkalis, appropriate handling procedures should be followed.
