Description and Uses

Trimethylolpropane tris(3-mercaptopropionate) is a colorless crystalline compound that dissolves in water and polar solvents but remains insoluble in nonpolar solutions. It is a crucial cross-linking agent in the formulation of polymers, resins, and coatings and is used as a photoinitiator for UV-reactive coatings and inks. Additionally, Trimethylolpropane tris(3-mercaptopropionate) acts as a chelating agent in the treatment of heavy metal toxicity, and it is used to modify high internal phase emulsions to extract heavy metals from water.

Trimethylolpropane tris(3-Mercaptopropanoate) can be used to prepare UV curing environmentally friendly nail polish.
