The Henry's Law constant for sec-butyl mercaptan is estimated as 7.3X10-3 atm-cu m/mole (SRC) derived from its vapor pressure, 80.7 mm Hg (1), and water solubility, 1.32X10+3 mg/L (2). This Henry's Law constant indicates that sec-butyl mercaptan is expected to volatilize rapidly from water surfaces (3) 1-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, 1-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 1-butanethiol is so strong that the human nose can easily detect it. 1-Butanethiol is a volatile sulfur-containing odorous compound that is reported to occur in skunk oil.

These are organic compounds containing the thiol functional group linked to an alkyl chain. 2-Methyl-1-butanethiol is an extremely weak basic (essentially neutral) compound (based on its pKa)

cm-2 for (S)-2-butanethiol and (R)-2-butanethiol, respectively, close to the anticipated value for 2 molecules per cell of 5.8 10-10 mol cm-2.The adsorbate coverage is therefore 25%. Repetition of this procedure using a 50:50 mixture of the S-sec-butyl ethanthio- ate enantiomers yields a higher-density SAM indistinguishabl In addition, thiols prepared from alkanes retain the -e in the name of the alkane—for example, butanethiol and ethanethiol as opposed to the alcohols butanol and ethanol. The ―SH group of a thiol is known as a mercapto group, and therefore the prefix mercapto- may be included in the names of certain compounds—for example, 2.
