Understanding the intrinsic chemical properties and diverse applications of key reagents is fundamental for B2B professionals in chemistry and manufacturing. Phosphorus Oxybromide (CAS 7789-59-5), often denoted as POBr3, is a compound of significant industrial interest due to its potent reactivity and versatility. This article explores its chemical profile and the various sectors that rely on it, offering insights for procurement and R&D specialists. As a leading chemical supplier, we aim to provide comprehensive information on compounds like POBr3.

Unveiling the Chemical Profile of Phosphorus Oxybromide

Phosphorus Oxybromide is an inorganic compound characterized by its molecular formula, POBr3, and a molecular weight of approximately 286.69 g/mol. It typically presents as a colorless to pale yellow crystalline solid or a molten liquid if heated above its melting point of 56°C. A notable characteristic is its pungent, irritating odor, often compared to that of bromine.

Key physicochemical properties include:

  • Density: Approximately 2.82 g/mL at 25°C.
  • Boiling Point: It decomposes around 200°C.
  • Solubility: While it reacts vigorously with water, it exhibits good solubility in organic solvents such as ether, benzene, chloroform, and carbon disulfide.
  • Reactivity: POBr3 is highly reactive, particularly with nucleophiles and protic solvents like water. This reactivity is harnessed in synthetic chemistry but also necessitates careful handling and storage in dry, inert conditions to prevent decomposition and the release of hazardous fumes.
  • Purity: For industrial applications, particularly in pharmaceuticals and advanced materials, high purity grades (e.g., ≥98.0% assay) are commonly sought after.

Diverse Industrial Applications of POBr3

The unique chemical attributes of Phosphorus Oxybromide lend themselves to several critical industrial uses:

  • Brominating Agent in Organic Synthesis: POBr3 is a powerful reagent for introducing bromine atoms into organic molecules. This is essential for synthesizing complex intermediates, including those used in the pharmaceutical industry and for creating specialty chemicals. Researchers looking to buy Phosphorus Oxybromide for specific synthetic pathways will find its controlled reactivity highly advantageous.
  • Precursor for Flame Retardants: It serves as a vital raw material in the manufacturing of brominated flame retardants. These compounds are critical for enhancing the fire safety of plastics, textiles, and electronic components, making POBr3 an important part of the materials science supply chain.
  • Catalysis and Other Reactions: Its Lewis acidic nature allows it to function as a catalyst in certain organic reactions, and it is also employed in specific chemical processes requiring halogen transfer.
