Cuprous Bromide (CuBr) is a significant inorganic compound widely utilized across various scientific and industrial sectors. Its unique chemical and physical attributes make it a valuable material for catalysis, synthesis, and specialized applications. For researchers, chemists, and procurement specialists, a thorough understanding of CuBr is crucial for its effective and safe utilization. As a key manufacturer and supplier of CuBr, we aim to provide this essential information.

Chemical and Physical Properties of CuBr:

Cuprous Bromide (CAS 7787-70-4) is characterized by its formula CuBr and a molecular weight of 143.45 g/mol. Key properties include:

  • Appearance: Typically presents as a white cubic crystal or powder. However, it can oxidize in air or be impure, leading to pale green or even grayish-brown hues.
  • Melting Point: Approximately 497°C, indicating good thermal stability for many applications.
  • Solubility: Insoluble in water, acetone, and acetic acid, but soluble in hydrobromic acid, hydrochloric acid, nitric acid, and ammonia.
  • Reactivity: It is a copper(I) halide, prone to oxidation to copper(II) species. It participates in various coordination complexes and is a key reagent in redox reactions.

Synthesis Methods:

The preparation of Cuprous Bromide can be achieved through several methods:

  • Reduction of Copper(II) Salts: A common laboratory and industrial method involves the reduction of copper(II) bromide or copper(II) sulfate in the presence of bromide ions, often using reducing agents like sulfur dioxide or metallic copper. For instance, the reaction of copper(II) bromide with sulfite: 2 CuBr₂ + H₂O + SO₃²⁻ → 2 CuBr + SO₄²⁻ + 2 HBr.
  • Reaction of Copper(I) Oxide with Hydrobromic Acid: This method is also employed, where copper(I) oxide reacts with hydrobromic acid under controlled conditions.

The choice of synthesis method impacts the purity and morphology of the final product, influencing its suitability for specific applications. When you buy Cuprous Bromide, understanding its synthesis can inform your quality assessment.

Safety Guidelines for Handling CuBr:

While essential, CuBr requires careful handling. As a chemical compound, safety precautions are paramount:

  • Personal Protective Equipment (PPE): Always wear appropriate PPE, including safety goggles, gloves, and a lab coat, to prevent skin and eye contact.
  • Ventilation: Handle CuBr in a well-ventilated area or under a fume hood to avoid inhalation of dust or any potential fumes.
  • Storage: Store CuBr in tightly sealed containers in a cool, dry, and well-ventilated warehouse, away from heat sources and incompatible materials like oxidizing agents.
  • Disposal: Dispose of waste CuBr and contaminated materials according to local hazardous waste regulations.
