ABSTRACT
A fragrance is defined as a sweet or delicate odor of flowers or other growing things. A fragrance can also be derived from scents given off by animals, as would be the case in the family of musk-related chemicals. Fragrance chemicals are often extracted directly from plant or animal material, but as specific fragrance chemical structures are identified, fragrance manufacturers are producing synthetic fragrance chemicals. There is an advantage to using synthetic fragrance chemicals because of limitations on the supply of some natural (plant-and animalderived) fragrances and the lot-to-lot variability in their composition. New synthetic fragrances can be developed by simple changes to the parent molecule. This provides the fragrance chemist with an almost unending supply of novel fragrance ingredients.
