Dodecan-1-ol
A primary alcohol that is dodecane in which a hydrogen from one of the methyl groups is replaced by a hydroxy group. It is registered for use in apple and pear orchards as a Lepidopteran pheromone/sex attractant, used to disrupt the mating behaviour of certain moths whose larvae destroy crops. — ChEBI
