· JVASP-122443· K3Au3I8

K3Au3I8 is an intermetallic compound combining potassium, gold, and iodine—a rare material that exists primarily in research contexts rather than established industrial production. This compound belongs to the family of gold halides and mixed-metal iodides, which are investigated for their potential in electronic, photonic, and solid-state chemistry applications. Limited commercial availability and specialized synthesis requirements make this a material of interest primarily for academic research and experimental device development rather than conventional engineering applications.

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.
