Chemical: Copper chloride (CuCl)

Copper chloride (CuCl) is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Copper chloride (CuCl) are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)

Copper (I) chloride: Does not have an individual approval but may be used under an appropriate group standard

Harmful if swallowed; [MSDSonline] Acute copper poisoning after ingestion can cause liver injury, methemoglobinemia, and hemolytic anemia. Acute renal failure may result, secondary to massive hemoglobinuria. [Goldfrank, p. 1259] Classified as category I for skin and eye irritation (corrosive); Category II for acute oral and dermal exposure (moderate toxicity); Category III for acute inhalation exposure (low toxicity); Positive results in dermal sensitization studies; [Reference #2] May cause irritation; Harmful by ingestion; [Alfa Aesar MSDS] See Copper.

Cuprous chloride

Severe marine pollutant

Copper is mainly absorbed through the gastrointestinal tract, but it can also be inhalated and absorbed dermally. It passes through the basolateral membrane, possibly via regulatory copper transporters, and is transported to the liver and kidney bound to serum albumin. The liver is the critical organ for copper homoeostasis. In the liver and other tissues, copper is stored bound to metallothionein, amino acids, and in association with copper-dependent enzymes, then partitioned for excretion through the bile or incorporation into intra- and extracellular proteins. The transport of copper to the peripheral tissues is accomplished through the plasma attached to serum albumin, ceruloplasmin or low-molecular-weight complexes. Copper may induce the production of metallothionein and ceruloplasmin. The membrane-bound copper transporting adenosine triphosphatase (Cu-ATPase) transports copper ions into and out of cells. Physiologically normal levels of copper in the body are held constant by alterations in the rate and amount of copper absorption, compartmental distribution, and excretion. (L277, L279)

Used to produce other copper compounds and in the production of silicone polymers, ethylene-propene rubbers, dialkyl carbonates, and acrylonitrile; Also used to purify carbon monoxide and to produce phthalocyanine pigments; Occurs in nature as nantokite; [Ullmann] Used as a catalyst for organic reactions, decolorizer, catalyst, and desulfuring agent in the petroleum industry, in denitration of cellulose, as condensing agent for soaps, fats, and oils, and in gas analysis to absorb carbon monoxide; [Merck Index] Used in Korea as a raw material for coloring agents and as a catalyst for CO and H2 production; [Reference #1] Used to control plant root growth in nursery pots (incorporated into the plastic); [Reference #2]

Petroleum Production and Refining [Category: Industry]

Copper(I) chloride is as a precursor to the fungicide copper oxychloride. It is also used in organic and polymer chemistry. (L292)
