Gold(III) chloride
CAS 13453-07-1
Gold trichloride is the anhydrous entry to gold(III) chemistry — a π-acid catalyst for alkyne activation in its own right and the precursor to N-heterocyclic carbene and phosphine gold complexes.

Where AuCl₃ is used
Homogeneous gold catalysis
An active Lewis-acidic catalyst for alkyne hydration, hydroamination and cycloisomerization — the chemistry that launched the modern gold-catalysis field.
Gold complex synthesis
The anhydrous precursor for NHC–gold and phosphine–gold chloride complexes used in catalysis and metallodrug research.

Frequently asked questions
How is pricing structured?
Quotes reference the day's gold price on assayed contained metal plus a stated conversion charge, lockable at order confirmation.
What documentation is included?
Every lot ships with a certificate of analysis stating assayed metal content, plus an English SDS. ICP trace-metal panels are available on request.
Do you take back spent material?
Yes — residues and off-spec lots are assayed on receipt and the recovered metal credited against your next order.
