· C2 O6 Cd2

Cadmium oxide (CdO) is an inorganic semiconductor compound belonging to the metal oxide family, typically encountered as a crystalline solid with wide bandgap properties. While cadmium oxide has historical significance in optoelectronic research and transparent conductor applications, its use is severely limited in most industries due to cadmium's toxicity and strict regulatory restrictions (RoHS, WEEE directives in electronics; CRA and other environmental regulations globally). Modern applications are largely confined to specialized research contexts, legacy systems, and niche high-temperature or radiation-resistant electronics where safer alternatives are unavailable.

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.
