Descripción

General description

ʟ-Penicillamine(3,3-Dimethyl-L-cysteine) is good water-soluble compound. It is generally used as a metal-chelating agent.

Application

ʟ-Penicillamine is used:

• In the synthesis of Cu nanoclusters (CuNCs) from copper(II).
• In the preparation of ligands based onpyridine-2,6-dicarboxylic acid, which is in combination with cobalt (III) to convert acetonitrile to acetamide and benzonitrile to benzamide.
