The two substrates of this enzyme are cinnamyl alcohol and oxidised nicotinamide adenine dinucleotide phosphate (NADP+). Its products are cinnamaldehyde, reduced NADPH, and a proton.[1][2][3][4]

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 cinnamyl-alcohol:NADP+ oxidoreductase. Other names in common use include cinnamyl alcohol dehydrogenase, and CAD. This enzyme participates in phenylpropanoid biosynthesis.
