General description

6-Mercaptopyridine-3-carboxylic acid (MPCA, 6-mercaptonicotinic acid, MNA) is a bifunctional ligand, made up of pyridine moiety containing carboxylic and mercapto group. The electrochemical properties of self-assembled monolayers (SAMs) of MNA on gold electrode have been described.

Application

6-Mercaptopyridine-3-carboxylic acid may be used in the following processes:
  • Fabrication of nanowell based sensors for the detection of improvised explosive devices (IEDs).
  • Functionalization of gold nanoparticles (AuNPs) for the highly sensitive and selective detection of Cd2+ in colorimetric assay.
  • Preparation of thiolated chitosans, which are thiolated biopolymers exhibiting mucoadhesive, enzyme inhibitory, and permeation enhancing properties.
  • Synthesis of Zinc(II) coordination polymers.
