Trichloroacetyl chloride is the acyl chloride of trichloroacetic acid. It can be formed by reacting chlorine with acetyl chloride or acetaldehyde in the presence of activated charcoal, or by the isomerisation of tetrachloroethylene oxide via heating. It is used in the manufacture of pharmaceuticals and plant protection compounds.^[4]

Caesium hydroxide is a strong base containing the highly reactive alkali metal caesium, much like the other alkali metal hydroxides such as sodium hydroxide and potassium hydroxide. It is the strongest of the five alkali metal hydroxides. Fused caesium hydroxide has applications in bringing glass samples into a solution for analytical purposes in the commercial glass industry and a defense waste processing facility as it is able to dissolve glass by attacking its silica framework. The melting process is carried out in a nickel or zirconium crucible. Caesium hydroxide fusion at 750°C produces complete dissolution of glass pellets.
