The molecule is a para-disubstituted benzene with substituents at carbons 1 and 4.

- At carbon-1: the ring is bonded to a straight, unbranched n-heptyl chain (a fully saturated seven-carbon chain, attached through its first carbon).

- At carbon-4 (para to the heptyl group): the ring is bonded to an oxime of formaldehyde, attached through the nitrogen atom. In detail, the ring carbon is single-bonded to nitrogen; that nitrogen is double-bonded to a methine carbon; and the methine carbon bears one hydrogen and a hydroxyl group (-OH).
