Application

  • Synthesis of nanoparticles: A study on the functionalization of multiwalled carbon nanotubes using Cysteaminium chloride was conducted, resulting in the synthesis of gold nanoparticles decorated carbon nanotubes. This highlights its application in nanomaterials fabrication and potential uses in various technological fields (Duc Chinh et al., 2019).
  • Pharmaceutical applications: Cysteaminium chloride′s chemical properties are utilized in the synthesis of thiol-functionalized chitosan nanoparticles. These nanoparticles are designed to adsorb heavy metals from aqueous solutions, demonstrating a vital application in environmental management and potential for pharmaceutical waste treatment (Nemati et al., 2019).
  • Crystallography: Research involving Cysteaminium chloride has contributed to the discovery of a monoclinic polymorph of cysteamine hydrochloride, which is significant for its implications in crystal engineering and materials science, providing insights into molecular and crystal structure interactions (Ahmad et al., 2009).
