一般說明

4-Methyl-2-oxovaleric acid, also known as α-ketoisocaproic acid (KIC), is a metabolite of leucine. It is commonly used as a building block in the synthesis of leucine and its derivatives, and it plays a role in amination reactions and asymmetric synthesis. Additionally, KIC serves as an intermediate in the formation of Strecker aldehydes.
