2-Methylpentanal is an organic compound with the formula CH₃CH₂CH₂CH(CH₃)CHO. It is a colorless liquid. The compound is a chiral aldehyde. It serves as a precursor to the commercial tranquilizer meprobamate. It is prepared by aldol condensation of propionaldehyde followed by dehydration and hydrogenation of the aldol product.^[1]
