3-MPSNa (3-Mercapto-1-propanesulfonic acid, sodium salt)
(CAS No. 17636-10-1)
(Figure 1)
-
● Makes it possible to dissolve materials that are insoluble in water soluble (Fig. 1)
-
A water-soluble functional group can be created for water-insoluble compounds, via S (sulfur).
It is reported that phthalocyanine can now be made soluble (JP 2003-12952). -
● Really? Is this a sulfur compound? Amazingly little odor
-
Compared with other mercaptans, it has extremely little odor.
-
● It can be used as a metal surface treatment agent
-
Performs as a metal rust preventive and rust remover.
It also serves as an additive for electrolytic copper plating (JP 2012-127003). -
● Has high chain transfer ability
-
It can be used as a polymerization regulator in the radical polymerization of water-soluble vinyl monomers (JP 2005-029747).
