Copper(II) chloride (CuCl2)
Synonym(s): Copper chloride. Cupric chloride
Chapman Hall Number: JVX76-V
CAS Registry Number: 7447-39-4
Related CAS Registry Numbers(s): 1344-67-8
CuCl2

Molecular Formula: Cl2Cu
Molecular Weight: 134.451
Accurate Mass: 132.877302
Percentage Composition: Cl 52.74%; Cu 47.26%
General Statement: Struct. contains chains of square planar CuCl2CuCl2
Use/Importance: Catalyst; used in petroleum industry as deodorising, desulfurising and purifying agent; in refining Cu, Ag, Au; in photography as fixer and desensitiser, in manuf. of acrylonitrile, in pigments, as feed-additive, wood preservative, disinfectant. Used in org. synth. as a chlorinating agent, oxidising agent and Lewis acid. Starting material for Cu compds.
Physical Description: Deliquescent yellow to brown microcryst. powder
Melting Point: Mp 630 (extrap.)
Solubility: Sol. H2O, EtOH, Me2CO
Other Data: Part. dec. 300 to CuCl + Cl2. Mp of 498 often reported is for mixt. CuCl2/CuCl. Forms dihydrate in moist air
Hazard Toxicity: Irritating to skin, mucous membranes. Ingestion of large amounts of Cu salts (15-75 mg Cu) causes gastrointestinal disturbances. Haemolysis, hepatotoxic and nephrotoxic effects, and death have also been reported from acute exposure. Chronic Cu toxicity is not known in normal human beings but the toxicity of Cu in patients with Wilson's disease is well documented. LD50 (rat, orl) 584 mg/kg
RTECS Accession Number: GL7000000
