General description

2-Iminothiolane hydrochloride (2-IT.HCl), a protein modification reagent, is commonly employed to attach thiol groups to proteins and peptides. Raman spectroscopic analysis of hair keratin fibers modified with 2-IT.HCl showed the formation of new disulfide groups.

Application

2-Iminothiolane hydrochloride has been used in the synthesis of thiolated PEG (poly(ethylene glycol). It may be used to synthesize PLA-SH (polyethylene glycol-thiol) and PLA-PEG-SH (polyethylene glycol–polylactic acid-thiol).
Thiolating reagent for primary amines. Reacts at pH 7-10 by amidine bond to present free sulfhydryl. Useful in preparation of disulfide and/or thioether linked conjugates.

Other Notes

Note that the amidine linkage preserves original primary amine positive charge. Incorporates a five atom linker.
