Aplicaciones

Used as intermediates in pharmaceutical chemical and organic synthesize. It can react with N-benzoyl-glycine in the presence of 4-(dimethylamino)pyridine and acetic anhydride to produce 4-(1-ethoxy-propylidene)-2-phenyl-4H-oxazol-5-one. It is also applied as a starting material in the synthesis of Triethyl orthoacrylate. Triethyl orthopropionate is also commonly used in Claisen rearrangement reactions that yield γ,δ-unsaturated esters.

Notas

Store away from water/moisture and oxidizing agents. Keep the container tightly closed and place it in a cool, dry and well ventilated condition. Store under inert gas. Protect against electrostatic charges. Keep ignition sources away.
