Cuprous Chloride is an inorganic copper(I) salt supplied as a chemical raw material, also referred to as copper(I) chloride or cuprous chloride in technical documentation. Identified by CAS 7758‑89‑6, it contains copper in the +1 oxidation state and exhibits characteristic coordination and redox behavior in controlled chemical systems. It is typically applied as an inorganic catalyst or reagent in industrial synthesis and processing environments where defined copper(I) activity and chloride availability are required. From a supply perspective, the material is available with competitive factory pricing, customized specifications, and supporting documentation including MSDS, TDS, COA, suitable for regulated bulk supply for industrial use.

FAQ - Technical & Supply Chain
-
Q:
Are cuprous chloride and copper(I) chloride the same substance?
A: Yes. Cuprous chloride is the traditional name for copper(I) chloride, and both correspond to CAS 7758‑89‑6. -
Q:
Is cuprous chloride different from copper(II) chloride?
A: Yes. Cuprous chloride contains copper in the +1 oxidation state, while copper(II) chloride contains copper in the +2 state and is a different compound with a different CAS number. -
Q:
Is cuprous chloride mainly supplied as an industrial reagent or catalyst?
A: It is commonly supplied as an inorganic reagent or catalyst for industrial chemical processing rather than as a finished end‑use product.
