Product Name:2-Cyano-3,5-difluoropyridine
English Name:2-Cyano-3,5-difluoropyridine
CAS No.:298709-29-2
Aliases:3,5-Difluoro-2-pyridinecarbonitrile, 3,5-Difluoro-2-pyridyl cyanide
Molecular Formula:C6H2F2N2
Physical Properties:Molecular weight 140.09. It appears as a colorless to light yellow transparent liquid or low-melting solid at room temperature with a characteristic odor. Density is approximately 1.34 g/cm³, boiling point is approximately 192°C, and flash point is approximately 78°C. It is readily soluble in organic solvents such as methanol, ethanol, dichloromethane and ethyl acetate, but sparingly soluble in water. It is sensitive to light and heat; recommended storage under sealed, light-protected, dry and low-temperature conditions.
Uses:Used as an intermediate in pharmaceuticals, agrochemicals and fine chemicals for the synthesis of fluorinated pyridine-containing bioactive molecules. In medicinal chemistry, it can be applied to prepare kinase inhibitors and antiviral/antitumor drug candidates; in agrochemistry, it is used for the synthesis of insecticides, herbicides and fungicides.
Technical Specifications:
Assay ≥ 98%
