PROPYNAL Usage And Synthesis

Uses

2-Propynal is hypothesized to be a possible metabolite of pargyline, a monoamine oxidase inhibitor that is used as an antihypertensive agent. 2-Propynal is also known to induce hepatocyte toxicity in vivo in rats.

Definition

ChEBI: Prop-2-ynal is a ynal and a terminal acetylenic compound. It has a role as a mouse metabolite.

Enzyme inhibitor

This aldehyde (FW = 54.048 g/mol; CAS 624-67-9), also known as propynal, synthesized from propargyl alcohol, is an irreversible inhibitor of aldehyde dehydrogenases.
