In enzymology, an octanol dehydrogenase (EC1.1.1.73) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are 1-octanol and NAD, whereas its 3 products are 1-octanal, NADH, and H.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD or NADP as acceptor. The systematic name of this enzyme class is octanol:NAD oxidoreductase. This enzyme is also called 1-octanol dehydrogenase.
