Product Name:Nonafluoropentanoic acid
English Name:Nonafluoropentanoic acid
CAS No.:2706-90-3
Aliases:Perfluoropentanoic acid, Perfluorovaleric acid
Molecular Formula:C5HF9O2
Physical Properties:Molecular weight: 264.05. Appearance: clear light yellow to light brown liquid. Density: 1.713 g/mL at 25°C. Boiling point: 140°C. Flash point: 140°C. Refractive index: 1.294 (n20/D). Partly soluble in water. Acidity coefficient (pKa): approximately 0.40±0.10 (predicted).
Uses:Used as an organic synthesis intermediate and industrial production raw material. In the biomedical field, it can be used as a propellant for pressurized metered-dose inhalers and as an ultrasound contrast agent. As an emulsifier, it is used in polymer dispersion, fire-fighting foam, anti-staining agents, paints and coating additives. It can also be used as a strong cation exchange agent for ion-pair chromatography.
