General description

Cesium hydroxide is a strong base that can be used in organic synthesis, as a catalyst, and as an intermediate in the production of cesium compounds.

Application

Cesium hydroxide monohydrate can be used:

  • As a catalyst to prepare unsymmetrical Bis-allyl ethers via dimerization of Baylis-Hillman adducts.
  • As a dopant to fabricate vanadium oxide thin films as a hole extraction layer for perovskite solar cells.
  • As an initiator for ring opening polymerization of monosubstituted oxiranes.
  • As a promoter to synthesize secondary amines via chemoselective N-alkylation.

(13)C metabolic MRI using hyperpolarized (13)C-bicarbonate enables preclinical detection of pH. To improve signal-to-noise ratio, experimental procedures were refined, and the influence of pH, buffer capacity, temperature, and field strength were investigated. Bicarbonate preparation was investigated. Bicarbonate was prepared and

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.
