Anwendungen

Ethyl glyoxylate is widely used as an intermediate in the synthesis of pharmaceuticals (high reactivity of aldehyde function). It is used in the synthesis of a biodegradable polymer, poly(ethyl glyoxylate). It is actively involved in the Friedel-Crafts alkylation reactions with thiophenes to give the corresponding secondary alcohols.

Bemerkungen

Air sensitive. Store in cool place. Keep container tightly closed in a dry and well-ventilated place.
