Red Phosphorus Canada
This Thermo Scientific Chemicals brand product was originally part of the Acros Organics product portfolio. Some documentation and label information may refer to the legacy brand. The original Acros Organics product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals. Phosphorus, red, 97%, pure, powder
Red phosphorus is a stable, versatile, and essential elemental chemical widely used across industrial manufacturing, material science, and chemical synthesis. Unlike white phosphorus, red phosphorus is non-luminous, non-self-igniting in air under ambient conditions, and significantly less toxic, making it the preferred commercial standard for high-performance applications.
Key Applications & Uses
-
Flame Retardancy: Serves as a highly effective halogen-free flame retardant in engineering polymers, electronics enclosures, and industrial plastics.
-
Chemical Synthesis: Functions as a vital reagent and catalyst substrate in organic synthesis and fine chemical production.
-
Match & Pyrotechnic Manufacturing: Acts as the primary active friction agent on safety match strike pads and specialized pyrotechnics.
-
Semiconductor & Electronics: Used in high-purity semiconductor doping and advanced battery energy storage research.
Safety & Handling
Red phosphorus is classified as a Flammable Solid (Category 1) and carries long-term aquatic hazard risks. Standard safety protocols require storing containers tightly sealed in a cool, dry, well-ventilated area away from heat, open flames, and strong oxidizing agents. Personal protective equipment (PPE)—including protective gloves, safety goggles, and proper dust masks—should be worn during handling.
