Copper(I) 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 2728 (OTTO)Copper(I) chloride, ≥99% Cas 7758-89-6 - used in the synthesis of copper nanoring structures. It has also been used as a precursor for the fabrication of ordered array of TiO2 nanoparticles on the conductive nitrogen-doped graphene (NG).
