4-Oxopentanal Chemical Properties,Usage,Production

Uses

4-Oxopentanal is an intermediate used to prepare enantiopure sulfinimines. It is also used in the synthesis of 2-pyridinone derivatives as HIV-1-specific reverse transcriptase inhibitors.

Definition

ChEBI: 4-oxopentanal is a ketoaldehyde that is pentanal substituted by an oxo group at position 4. It has a role as a metabolite.
