Description

4,4,5,5,6,6,7,7,7-Nonafluoro-1-heptanol (CAS No. 83310-97-8) is a high-purity fluorinated alcohol with the molecular formula C₇H₇F₉O. This specialty chemical features a linear heptanol backbone with a terminal hydroxyl group and a perfluorinated butyl segment, offering unique hydrophobic and oleophobic properties. With an IUPAC name of 4,4,5,5,6,6,7,7,7-nonafluoroheptan-1-ol, it is supplied as a clear, colorless to pale yellow liquid (purity typically ≥95%) with a density of ~1.6 g/mL at 25°C. The compound’s exceptional fluorine content makes it valuable for surface modification, polymer synthesis, and as a building block for fluorinated surfactants. Proper storage under inert atmosphere at 2-8°C is recommended to maintain stability.

Key applications include:

• Intermediate for fluorinated surfactants and polymers
• Surface energy modifier in coatings
• Hydrophobic agent for textile treatments
• Specialty solvent for fluorochemical processes

Available in research quantities (100mg to 100g) with optional certificate of analysis. Hazard classification: Skin irritant (Category 2), Eye irritant (Category 2).
