Butanethiol also known as butyl mercaptan is a volatile clear to yellowish liquid with a fetid (extremely foul-smelling) odor commonly described as skunk odor. In fact butanethiol is structurally similar to several major constituents of a skunk’s defensive spray but is not actually present in the spray. The scent of butanethiol is so strong that the human nose can easily detect it in the air at concentrations as low as 10 parts per billion.
