· AuCl

Gold chloride (AuCl) is an intermetallic or ionic compound combining gold with chlorine, belonging to the family of precious metal halides. It is primarily encountered in laboratory and industrial chemistry settings rather than as a bulk structural material, where it serves as a precursor for gold plating solutions, catalyst synthesis, and specialized chemical synthesis routes. Engineers and chemists select AuCl-based systems for applications requiring gold's superior corrosion resistance and electrical conductivity in thin-film or coating form, though it is not typically used as a load-bearing metal component in conventional engineering design.

Regulatory Screening

Environmental

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.
