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 a common thiol monomer reacted with alkenes in the thiol-ene reaction to form polymeric networks. [3] Being functionalized with four thiol groups, it can react with multifunctional alkenes to form thiol-ene networks.
The suffix-oate is the IUPAC nomenclature used in organic chemistry to form names of compounds formed with ester. They are of two types: They are of two types: Formed by replacing the hydrogen atom in the –COOH by some other radical , usually an alkyl or aryl radical forming an ester .
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-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.
Often, acrylate refers to esters of acrylic acid, the most common member being methyl acrylate. These acrylates contain vinyl groups . These compounds are of interest because they are bifunctional : the vinyl group is susceptible to polymerization and the carboxylate group carries myriad functionalities.
[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.
3,4-Dihydroxyphenylacetic acid (DOPAC) is a metabolite of the neurotransmitter dopamine. Dopamine can be metabolized into one of three substances. Dopamine can be metabolized into one of three substances.
