Cuprous chloride, is the lower chloride of copper, with the formula CuCl. The substance is a white solid sparingly soluble in water, but very soluble in concentrated hydrochloric acid. Impure samples appear green due to the presence of copper(II) chloride.
C 2727 (OTTO) Cuprous chloride, GR 97%+ Cas 7758-89-6 - used as a catalyst as well as a reagent in many organic reactions including Gatterman-Koch, Sandmeyer, Grignard and Gilman reactions. It catalyzes 1,4-addition of Grignard reagents to alpha,beta-unsaturated ketones. C 2727 (OTTO) Cuprous chloride, GR 97%+ Cas 7758-89-6 - used as a doping salt to enhance the cationization of polystyrene in matrix-assisted laser desorption/ionization mass spectrometry. It is also an intermediate formed in the Wacker process.
