Arsenic trioxide

Arsenic trioxide (CAS 1327-53-3), also known as white arsenic, is an inorganic oxide sourced for pharmaceutical manufacturing and metallurgical processing. It functions as a biocidal and chemical intermediate in tightly regulated industrial and medical supply chains. In oncology drug manufacturing, it is the active pharmaceutical ingredient in treatments for acute promyelocytic leukemia, requiring pharmaceutical-grade supply with strict purity documentation.

Non-ferrous metal refining operations use it as a byproduct intermediate in copper and gold smelting, where it must be captured, processed, and handled under controlled conditions. Glass manufacturing historically employed it as a fining agent to remove bubbles from molten glass, and this application persists in specialty glass production for specific industrial uses.

Wood preservation formulations, particularly in chromated copper arsenate systems, represent a legacy industrial use still active in certain regulated markets across the globe today. Arsenic trioxide is supplied as a white powder or in refined crystalline form. Pharmaceutical-grade material is available to USP and EP specifications for global distribution.

Documented purity levels are required for API supply chains. Technical-grade material is supplied for metallurgical and industrial applications, with buyers typically requiring a certificate of analysis. Compliance documentation is essential given the substance's regulatory status. Our supply chain ensures that all safety protocols and handling requirements are met for every industrial shipment.
