Gold(III) acetate
CAS 15804-32-7
Gold(III) acetate is the halide-free gold source for catalyst manufacture — the carboxylate precursor used where chloride would poison a supported gold catalyst or contaminate an electronic material.

Where Au(OAc)₃ is used
Halide-free supported gold catalysts
Chloride is a known poison in gold catalysis, promoting particle agglomeration. The acetate route gives Au/TiO₂, Au/CeO₂ and Au/C catalysts with finer, more stable dispersion for CO oxidation and selective oxidation chemistry.
Electronic and deposition chemistry
An organic-soluble, chloride-free gold source for MOD inks, thin films and metallization pastes where halide residues would corrode conductors.
Gold complex synthesis
A carboxylate entry to Au(III) coordination chemistry avoiding the halide metathesis steps needed from chloroaurates.
Storage and shipping
Storage. Store sealed, cool, dry and dark; light- and heat-sensitive.
Shipping. Ships in sealed glass with SDS; gold-compound export formalities confirmed per order.
Packaging. 1 g · 5 g · 25 g · 100 g
Synonyms
- Gold triacetate

Frequently asked questions
Why pay more than chloroauric acid?
In gold catalysis chloride is a poison that promotes sintering and lowers activity. The acetate eliminates a chloride-washing step and typically gives better dispersion and catalyst life — often cheaper in total than the chloride route.
How is pricing structured?
Quotes reference the day's gold price on assayed contained metal plus a stated conversion charge, lockable at order confirmation.
Are gold compounds harder to export?
Gold-bearing goods carry additional trade formalities in some lanes. We confirm the compliant routing and documentation per destination before accepting the order, so your shipment clears without surprises.
Do you take back spent material?
Yes — residues, spent catalyst and off-spec lots are assayed on receipt and the recovered gold credited against your next order.
