· JVASP-126980· Cu3I

Cu3I is a copper iodide intermetallic compound belonging to the copper halide family, characterized by a fixed stoichiometric ratio of three copper atoms per iodine atom. This material is primarily of research and emerging application interest rather than a commodity engineering material, with potential uses in semiconductor and optoelectronic device development where copper halides offer tunable band gaps and low toxicity compared to lead-based alternatives.

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.
