· JVASP-116451· As2Au

As₂Au is an intermetallic compound combining arsenic and gold in a 2:1 stoichiometric ratio. This is a research-phase material within the gold-arsenic binary system, studied primarily for its potential in semiconductor, optoelectronic, and specialized electronic applications where the combination of gold's conductivity and chemical stability with arsenic's semiconducting properties may offer distinct advantages. The material remains largely experimental; its development is motivated by the need for novel compounds in high-frequency electronics and integrated circuit architectures, though practical production and integration challenges limit current industrial deployment.

Export Control

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.
