The damascenones belong to a family of chemicals known as rose ketones, which also includes damascones and ionones. ''beta''-Damascenone is a major contributor to the aroma of roses, despite its very low concentration, and is an important fragrance chemical used in perfumery.〔(Rose (Rosa damascena) ), John C.
