4-MERCAPTOPHENYLACETIC ACID Chemical Properties,Usage,Production

Chemical Properties

4-MERCAPTOPHENYLACETIC ACID is White Powder

Uses

4-MERCAPTOPHENYLACETIC ACID is a redox buffer that increases the folding rate of disulfide-containing proteins realative to traditional buffers such as glutathione and glutathione-disulfide. A useful synthetic intermediate for the preparation of novel antiinflammatory agents.

Uses

4-Mercaptophenylacetic acid has been used in the preparation of small ubiquitin-like modifier peptides from bis(2-sulfanylethyl)amido peptide via sequential native chemical ligation.
It can be used:

On-resin preparation of peptide-^α thiophenylesters which are used in a chemical ligation process for the chemical synthesis of peptides.
In one pot deprotection of (acetamido-methyl)cysteine following native chemical ligation and/or desulfurization method for the preparation of peptides.
Palladium facilitated deprotection of N-terminal cysteine through native chemical ligation method for the preparation of synthetically challenging proteins.
