Kupfer(II)-nitrat-Trihydrat

Cu(NO₃)₂·3H₂O

Copper(II) nitrate trihydrate (Cu(NO3)2.3H2O, CAS 10031-43-3) is a hygroscopic blue-green crystalline copper salt, freely soluble in water and lower alcohols. In solution it dissociates into Cu2+ and NO3- ions: the nitrate behaves as a mild oxidizer while the Cu2+ can be reduced to metallic copper, calcined to copper oxide, or precipitated as a basic carbonate depending on the redox and pH path. Being halide-free, it suits processes where chloride contamination would poison a catalyst or plating bath. Primary uses: catalyst and supported-catalyst precursor (impregnation onto alumina or zeolite carriers), electroless and immersion copper surface-coating chemistry, CuO and Cu2O routes for ceramics and pigments, and laboratory/R&D synthesis. In bath formulation it is dosed to a target Cu2+ concentration rather than a fixed wt%, commonly a few to tens of g/L. Grade: Cu >=14% min, with Cl, Fe, Pb, Al, S and Si each <=10 ppm and Na/Mg <=20 ppm, verified by ICP-MS (Pb <=10 ppm, semiconductor-adjacent threshold). COA, MSDS and SDS per lot; FPC + CP on request. Multi-regional sourcing, CIF Marmara or Gebze bonded stock, ~20 MT FCL with smaller lots on request. Send your target Cu2+ spec and lot size for a COA-backed RFQ.
