S-Carboxyethylisothiuronium chloride

S-Carboxyethylisothiuronium chloride is a carboxylic acid quaternary ammonium salt containing a thiourea group. In the electroplating industry, S-Carboxyethylisothiuronium chloride serves as a core additive in electroless nickel plating and nickel electroplating systems. S-Carboxyethylisothiuronium chloride can be used in organic synthesis and biochemistry as a thiol-introducing reagent, carboxyethylation modifier, and mild reducing agent for the synthesis of pharmaceutical intermediates and the structural modification of proteins and peptides.
