Yellow Phosphorus, also known as white phosphorus, identified by CAS 12185-10-3 and the molecular formula P4, is a fascinating yet hazardous chemical compound. As a waxy, semitransparent solid, it typically appears white to light yellow and can even exhibit a light green color in the dark. Its properties, including spontaneous flammability in air and high reactivity, necessitate a thorough understanding of its handling and storage protocols for anyone in the chemical industry. Procurement managers and R&D scientists frequently search for 'yellow phosphorus properties' or 'safe handling of P4' to gather crucial information.

One of the most significant characteristics of Yellow Phosphorus is its pyrophoric nature, meaning it ignites spontaneously upon exposure to air. This property is both its key advantage for certain applications, like pyrotechnics, and its primary hazard. It is also highly toxic by inhalation and ingestion, and contact can cause severe skin burns. Due to these risks, Yellow Phosphorus must be stored and transported under water or an inert atmosphere to prevent contact with air. Its solubility in organic solvents like benzene and chloroform, contrasted with its insolubility in water, also dictates specific handling procedures. Safety Data Sheets (SDS) often highlight its classifications as a pyrophoric solid and acutely toxic substance, prompting users to search for 'Yellow Phosphorus SDS' or 'P4 chemical hazards'.

The industrial applications of Yellow Phosphorus are diverse, ranging from the production of other phosphorus chemicals like red phosphorus and phosphates (STPP, TSP) to its use in military ordnance and as a rodenticide. Each of these applications requires a specific purity level and consistent quality. For example, companies looking to 'buy yellow phosphorus 99.9% china' are often focused on its role as a precursor in sensitive chemical syntheses.
