· JVASP-29223· I2O5

Iodine pentoxide (I₂O₅) is an inorganic oxide ceramic composed of iodine and oxygen, belonging to the family of transition metal and halogen oxides. This material is primarily used as a catalyst and oxidizing agent in chemical processing, particularly in the catalytic oxidation of carbon monoxide to carbon dioxide in air purification systems and industrial gas treatment. I₂O₅ is notable for its strong oxidizing properties and thermal stability, making it a preferred choice over some alternative catalysts in applications where selective oxidation and low-temperature operation are required, though its use remains largely confined to specialized industrial chemistry rather than structural applications.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
