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. It is derived from the addition of hydrogen sulfide to acrylic acid.
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]
An ester of carboxylic acid. R stands for any group (organic or inorganic) and R′ stands for organyl group. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).
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.
An ester of a carboxylic acid.R stands for any group (typically hydrogen or organyl) and R ′ stands for any organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (R ′).

3-Mercaptopropionitrile is the organosulfur compound with the formula HSCH 2 CH 2 CN. [1] Containing both thiol and nitrile functional groups , it is a bifunctional compound . A colorless liquid, the compound has found some use as a masked form of thiolate.
[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.
Structure of the backbone of a cyanoacrylate polymer. In the same way that several variants of acrylic esters are known, so too are the corresponding polymers. Their properties strongly depends on the substituent. A large family of acrylate-like polymers are derived from methyl methacrylate and many related esters, especially polymethyl ...
