Description

General description

Butyl 3-mercaptopropionate (3MPA) is a monofunctional thiol that can be used as a cross-linker and chain transferring agent for controlling the molecular weight of the polymer. It can be used in the thiolene photopolymerization.

application

3MPA can be used as a ligand which can functionalize the quantum dots for the development of high luminescence light emitting diodes. It can also be used as a crosslinking monomeric unit for the preparation of thiol-acrylate based photopolymers.

Used as a reactant for thiol-yne photopolymerizations to form highly-cross-linked networks.
