CAS 7723-14-0 — Phosphorus, red

Red phosphorus is a non-metallic, highly reactive allotrope of phosphorus used primarily in safety matches, fireworks, and semiconductor manufacturing due to its stability and resistance to spontaneous ignition. This amorphous, deep red powder is inert under normal conditions but reacts vigorously at high temperatures. Catalogue details: CAS 7723-14-0, molecular formula P, molecular weight 30.974 g/mol, requires ambient storage with proper ventilation. Molekula supplies red phosphorus from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
