[Description]

2-Methyloctanal has a delicate, floral odor (rose- or lily-like). Prepared by heating methoxymethyl hexyl carbinol with oxalic acid or with anhydrous formic acid; also from hexanal and propionic aldehyde, Darzen’s synthesis of reacting methyl hexyl ketone and ethyl chloroacetate with sodium ethylate; the resulting ester is then hydrolyzed to the acid and this heated under vacuum.
