General description

Sulfur monochloride is a yellowish-red liquid widely used as a reagent and intermediate in organic synthesis. It is also employed in manufacturing pesticides, pharmaceuticals, and dyes.

Application

Sulfur monochloride can be used:
  • To synthesize functionalized aryl and heteroaryl disulfides from functionalized zinc organometallics.
  • As a reagent to prepare heterocycles with various numbers of sulfur atoms.
  • As a cross-linking agent to prepare rubber aerogels with enhanced thermal stability.
  • Toprepare macroporous cryogels of polyisobutylene and silica nanoparticles.

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.
