Pentaerythritol tetrakis(3-mercaptopropionate) is an organic compound which is derived from pentaerythritol fully esterified with four equivalents of 3-mercaptopropionic acid. It is a colorless liquid at room temperature. [1]
3-Mercaptopropionic acid (3-MPA) is an organosulfur compound with the formula HSCH 2 CH 2 CO 2 H. It is a bifunctional molecule, containing both carboxylic acid and thiol groups. It is a colorless oil.
Pentaerythritol was first reported in 1891 by German chemist Bernhard Tollens and his student P. Wigand. [5] It may be prepared via a base-catalyzed multiple-addition reaction between acetaldehyde and 3 equivalents of formaldehyde to give pentaerythrose (CAS: 3818-32-4), followed by a Cannizzaro reaction with a fourth equivalent of formaldehyde to give the final product plus formate ion.
[3] [4] The molecule's acrylate group functionality enables the molecule to do the Michael reaction with amines. It is therefore sometimes used in epoxy chemistry enabling a large reduction in cure time. [5] As the molecule has 4 functional acrylate groups it confers high cross-link density.

3-Hydroxypropionic acid is of interest as a bio-derived precursor to acrylic acid. [5]The polyester poly(3-hydroxypropionic acid) is a biodegradable polymer. [7] The method combines the high-molecular weight and control aspects of ring-opening polymerization with the commercial availability of the beta hydroxy acid, 3-hydroxypropionic acid which is abbreviated as 3-HP.
