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.
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).
It is a tetrafunctional acrylate ester used as a monomer in the manufacture of polymers. [1] As it is a polymerizable acrylate monomer, it is nearly always supplied with an added polymerisation inhibitor , such as MEHQ (monomethyl ether hydroquinone).
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 ′). [1]
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 .
