General description

1-Mercapto-2-propanol is a chain transferring agent that is the sixth series of hydrogen bonded 1,2-propanols which can be used to form polymeric chains with low molecular weight and short chain length.

Application

1-Mercapto-2-propanol can be used as a self-assembled monolayer on the gold surfaces with potential use in electrochemical applications. It may also be used as a chiral agent which can be used in the chemical analysis of enantiomers.
