A 2-(alkyl-cyclohexyl)-1-propanol is disclosed. The compound is represented by formula (I): ##STR1## wherein R.sub.1 and R.sub.2 individually represent a group selected from the members consisting of methyl-, ethyl-, n-propyl-, i-propyl-, t-butyl-, and sec-butyl groups, provided that the total carbon atoms of the R.sub.1 and R.sub.2 groups are 4 to 7; either R.sub.1 and R.sub.2 is a hydrogen atom, the other being a cyclohexyl group; or R.sub.1 and R.sub.2 together form a hexamethylene ring together with 2 carbon atoms in the cyclohexane ring. The compound possesses a long-lasting, woody, floral odor, and can be widely used as perfumery materials such as perfumes, soaps, shampoos, aromatic goods, and detergents.
