General description

Zinc chloride is a strongly hygroscopic deliquescentsolid widely used as a Lewis acid catalyst in a variety of organictransformations.

Application

Zinc chloride is used as a catalyst:
  • in Knoevenagel condensation of carbonyl substrates with acidic methylene reagents
  • in solvent-free synthesis of dihydropyrimidinones.
It may be used as chemical activating agents, zinc chloride in particular is the most widely used chemical in the preparation of activated carbon.

Methods of Synthesizing Monodisperse Colloidal Quantum Dots

Colloidal quantum dots (CQDs) are semiconducting crystals of only a few nanometers (ca. 2–12 nm) coated with ligand/surfactant molecules to help prevent agglomeration.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
