Diethyl fumarate DEF
CAS No.623-91-6
Alias: Diethyl fuMarat;Diethyl (2E)-but-2-ene-1,4-dioate;FuMaric acidethyl ester two;Diethyl fuMara;diethyl furmarate;trans-2-butenedioicaciddiethylester;DIETHYL TRANS-BUTENEDIOATE;DIETHYL FUMARATE
Molecular formula: C8H12O4
Relative molecular mass: 172.18
Structural formula:
1. Performance and use:
Diethyl fumarate is used as a pesticide or comonomer for the production of polystyrene.
Diethyl fumarate is unsaturated polyester resins are used in applications, such as reinforced glass fiber for boats, piping, bathtubs, roof panels, etc., and as protective coatings, finishes, and lacquers.
