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.
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.
Ethyl propionate is an organic compound with formula C 2 H 5 O 2 CCH 2 CH 3. It is the ethyl ester of propionic acid. It is a colorless volatile liquid with a pineapple-like odor. [3] Some fruits such as kiwis [4] and strawberries [5] contain ethyl propionate in small amounts.
Polypropylene glycol or polypropylene oxide is the polymer (or macromolecule) of propylene glycol. [1] Chemically it is a polyether, and, more generally speaking, it's a polyalkylene glycol (PAG) H S Code 3907.2000.
A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −C n H 2n−1. [2] Typically an alkyl is a part of a larger molecule. In structural formulae, the symbol R is used to designate a generic (unspecified) alkyl group. The smallest alkyl group is methyl, with the formula −CH 3 ...
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.
Ethyl 3-bromopropionate is the organobromine compound with the formula BrCH 2 CH 2 CO 2 C 2 H 5. It is a colorless liquid and an alkylating agent. It is prepared by the esterification of 3-bromopropionic acid. [1] Alternatively, it can be prepared by hydrobromination of ethyl acrylate, a reaction that proceeds in an anti-Markovnikov sense. [2]
