Red Phosphorus (CAS 7723-14-0) is a fundamental element with diverse industrial applications, ranging from pyrotechnics and flame retardants to the synthesis of critical pharmaceuticals and agrochemicals. For procurement managers and R&D scientists, a thorough understanding of its properties is essential for safe handling, effective application, and informed purchasing decisions. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier, provides insights into the key characteristics of this versatile fine chemical.

Key Properties of Red Phosphorus Powder

Red Phosphorus is an allotrope of phosphorus, distinguished from its more reactive counterpart, white phosphorus. Its most notable properties include:

  • Appearance: It typically presents as a fine red powder.
  • Solubility: Red Phosphorus is characterized by its insolubility in water, carbon disulfide, and ethanol, as well as most other organic solvents. This low solubility contributes to its stability in various formulations.
  • Purity: Industrial grades commonly achieve a purity of ≥98.0%. This high purity is crucial for consistent performance in demanding applications.
  • Reactivity: While significantly less reactive than white phosphorus, Red Phosphorus is still a flammable solid and a potent reducing agent. It can react with oxidizers and certain compounds under specific conditions. Its melting point is around 590°C.
  • Stability: It is relatively stable in air and does not spontaneously ignite under normal conditions, making it safer to handle and store compared to white phosphorus. However, it is often stabilized with additives like magnesium hydroxide to further enhance its safety profile.

Industrial Handling and Safety Considerations

Given its flammable nature, proper handling procedures for Red Phosphorus are paramount:

  • Storage: It should be stored in a cool, dry, well-ventilated area, away from sources of ignition, heat, and incompatible materials (especially oxidizers).
  • Handling: Minimize dust generation. Use appropriate personal protective equipment (PPE), including gloves, safety glasses, and respiratory protection, especially when handling large quantities.
  • Ignition Sources: Keep away from open flames, sparks, and hot surfaces. Static discharge can also be a source of ignition. Ensure proper grounding of equipment when transferring the material.
