In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called New polymer protecting group in oligonucleotide synthesis. 2-Hydroxyethyl phenyl thio ether of polyethylene glycol, published in 1974, which mentions a compound: 542-58-5, mainly applied to thymidine protection polyethylene glycol, Related Products of 542-58-5.
Bis[4-(2-hydroxyethylthio)phenylamino]polyethylene glycol condensed with the thymidine nucleotide I to give ∼90% of the corresponding phosphate-protected nucleotide. The protecting group was cleaved by sequential N-chlorosuccinimide oxidation and treatment with NaOH.
Here is just a brief introduction to this compound(542-58-5)Related Products of 542-58-5, more information about the compound(2-Chloroethyl acetate) is in the article, you can click the link below.
