Product Name:Dimethyl 2-fluoromalonate
English Name:Dimethyl 2-fluoromalonate
CAS No.:344-14-9
Aliases:Dimethyl fluoromalonate, Fluoromalonic acid dimethyl ester
Molecular Formula:C5H7FO4
Physical Properties:Colorless to light yellow transparent liquid with an ester-like odor. Relative density is about 1.22 g/cm³, boiling point is approximately 190°C, and flash point is about 75°C. Slightly soluble in water; soluble in common organic solvents such as ethanol, diethyl ether, acetone. Unstable to heat and alkali, prone to hydrolysis and defluorination.
Uses:Used as an organic synthesis intermediate, mainly for the preparation of fluorinated malonate derivatives and α-fluorocarboxylates. In the pharmaceutical industry, it is used to synthesize fluorine-containing drugs such as antiviral and antitumor agents, and it is also an important building block for agrochemicals and functional materials.
