General description
Sodium 3-mercapto-1-propanesulfonate forms self assembled monolayer via chemisorption on a gold-coated substrate[1].
Application
Sodium 3-mercapto-1-propanesulfonate (MPS) can be used to prepare tetrasubstituted organosilicon thioether by photochemical reaction with tetravinylsilane via thiol-ene reaction.[2] It can also be used as a capping agent to functionalize gold nanoparticles for potential applications in the field of radiotherapy and drug delivery.[3][4]
MPS can be also used in the preparation of Rh nanoparticles by liquid-phase reduction of rhodium (III) chloride.[5]

Hi, I was just wondering what the main impurities in this substance are, since the purity is only 90%? If the impurities are of different cations this will affect how I use this product compared with impurities to do with structural defects in the anion.
