    Cuprous Iodide CAS 7681-65-4

    Cuprous Iodide (CAS 7681-65-4) is a dense, white to brownish inorganic powder consisting of copper(I) cations and iodide anions, primarily utilized as a highly effective catalyst in organic synthesis and a heat stabilizer in nylon polymers. This Copper(I) iodide compound functions as a crucial reagent in Sandmeyer reactions and Ullmann condensations to facilitate carbon-heteroatom bond formation, while also serving as a key additive in Cuprous monoiodide formulations to enhance the thermal durability of industrial polyamides. To support industrial-scale requirements, we provide bulk supply with competitive factory pricing and ensure rigorous quality control through customized specifications alongside standard technical documentation, including MSDS, TDS, COA.

    Applications:
    It can be used as an organic synthesis catalyst, resin modifier,artificial rainfallagents, anode ray tube coverings, andAdd iodized saltSource of iodine in . Cerium is present in the 1,2- or 1,3-diamine ligand, and cuprous iodide can catalyze brominated aromatic hydrocarbons and brominationheterocyclic compoundsandVinyl bromideTransform into correspondenceiodidereaction. The reaction is generally inDioxanesolvent, toSodium iodideAs an iodination reagent.
    Aromatic iodide is generally more active than its counterparts chloride and iodide, so cuprous iodide can catalyze a series of thingsHalogenated hydrocarbonsinvolvedCoupling reactionsFor exampleHeck reaction, Stille reaction, Suzuki reaction, and Ullmann reaction. 2-bromo-1-octen-3-ol and 1-nonylene are presentBistriphenylphosphorus palladium dichloride, cuprous chloride and diethylamineWhen present, a coupling reaction occurs to produce 7-methylene-8-hexadecarbon-6-ol.

    FAQ - Technical & Supply Chain

    • Q:

      Is Cuprous Iodide (CAS 7681-65-4) chemically distinct from Copper(II) Iodide?

      A: Yes, this substance is the stable univalent copper salt (CuI), distinct from divalent copper iodide which is generally unstable and decomposes spontaneously under standard conditions.
    • Q:

      What is the primary role of this material in chemical manufacturing?

      A: It is typically applied as a catalyst for various coupling reactions involving aryl halides and as a stabilizing agent to prevent oxidative degradation in polyamide resin production.
