The major drawback of free thiols is their propensity to oxidize to disulfides. The acetyl-protected thiols are not only stable, but they actually form excellent quality monolayers (cf. Tour et al. J. Am. Chem. Soc. 117, 9529, 1995). In addition, the variety of headgroups we offer allows using these compounds as useful precursors for further syntheses.
