IUPAC NAME: butane-1-thiol

n-Butyl Mercaptan is a volatile, clear to yellowish liquid with a fetid (extremely foul-smelling) odor, commonly described as "skunk" odor. 
In fact, n-Butyl Mercaptan is structurally similar to several major constituents of a skunk's defensive spray but is not actually present in the spray.

The scent of n-Butyl Mercaptan is so strong that the human nose can easily detect it in the air at concentrations as low as 10 parts per billion. 
The threshold level for n-Butyl Mercaptan is reported as 1.4 ppb

n-Butyl Mercaptan is used as an industrial solvent, and as an intermediate for cotton defoliants.
n-Butyl Mercaptan is sometimes placed in the "stink bombs" and "stink perfumes" for pranksters.

n-Butyl Mercaptan is a natural product found in Mephitis mephitis with data available.
n-Butyl Mercaptan appears as a clear, colorless liquid

n-Butyl Mercaptan has a strong skunk-like odor. 
n-Butyl Mercaptan's flash point in range -18 to 43 °F. 

n-Butyl Mercaptan less dense than water
n-Butyl Mercaptan is slightly soluble in water. 

n-Butyl Mercaptan's vapors heavier than air.
n-Butyl Mercaptan is an alkanethiol.

n-Butyl Mercaptan's Chemistry:
n-Butyl Mercaptan is chemically classified among the thiols, which are organic compounds with molecular formulas and structural formulas similar to alcohols, except that the sulfur-containing sulfhydryl group (-SH) replaces the oxygen-containing hydroxyl group (-OH) in the molecule. 
n-Butyl Mercaptan's basic molecular formula is C4H9SH, and its structural formula is similar to that of the alcohol n-butanol. 

n-Butyl Mercaptan is prepared by the free radical catalyzed addition of hydrogen sulfide to 1-butene. 
Commercially, this is performed using ultraviolet light. 
n-Butyl Mercaptan is a thiol of low molecular weight, and it is highly flammable.

n-Butyl Mercaptan (Butanethiol) is a yellowish liquid with strong odor 
n-Butyl Mercaptan is used as an industrial solvent and intermediate in food nutritional applications as well as flavour and fragrance intermediate, agrochemical intermediates to maintain fertile land, grow crops and raise healthy livestock. 

Mixing with other products, n-Butyl Mercaptan is also used to formulate a cleaning product capable of removing iron scales from metal surfaces in steam generating equipment.
n-Butyl Mercaptan is useful for removing scale from metal surfaces. 

n-Butyl Mercaptan is used in food and nutritional applications as an agrochemical intermediate, steam boilers, feed water heaters, piping and heat exchangers and as lubricating oil additive.
