2-Methyloctanal is an organic compound classified as an aldehyde, characterized by its straight-chain structure with a methyl group attached to the second carbon of an octanal chain. Its molecular formula is C9H18O, indicating it contains nine carbon atoms, eighteen hydrogen atoms, and one oxygen atom. This compound typically appears as a colorless to pale yellow liquid with a distinctive fatty, slightly sweet odor. It is soluble in organic solvents but has limited solubility in water due to its hydrophobic hydrocarbon chain. 2-Methyloctanal is primarily used in the synthesis of various fragrances and flavoring agents, as well as in the production of surfactants and other chemical intermediates. Its reactivity is typical of aldehydes, allowing it to undergo oxidation to form corresponding carboxylic acids or participate in condensation reactions. Safety data indicates that, like many aldehydes, it should be handled with care due to potential irritant properties and the need for proper ventilation during use.

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.
