Arsenic Trioxide is a white crystalline solid primarily synthesized via the roasting of arsenic-containing ores. It serves as a critical intermediate in semiconductor manufacturing and glass production. Its chemical identity is defined by the molecular formula As₂O₃ and CAS number 1327-53-3.
This substance is highly toxic with severe carcinogenic risks. Strict PPE including respirators and chemical-resistant gloves is mandatory during handling. Storage must occur in sealed, corrosion-resistant containers within ventilated, locked facilities away from incompatible oxidizers.
