Silver tetrafluoroborate
CAS 14104-20-2
AgBF₄ is the halide-abstraction workhorse — the silver salt that strips chloride from metal complexes to generate cationic catalysts, and a weakly coordinating anion source across organometallic chemistry.

Where AgBF₄ is used
Catalyst activation
The standard reagent for abstracting halides from Au, Rh, Ir and Pd precatalysts to unleash cationic active species — consumed stoichiometrically alongside our precatalyst range.
Synthesis with weakly coordinating anions
Delivers the BF₄⁻ counterion in cationic complex isolation and serves as a mild Lewis-acid promoter in halide substitution chemistry.
Storage and shipping
Storage. Store sealed, dry and dark; hygroscopic and light-sensitive.
Shipping. Ships in sealed glass with SDS. Silver-bearing goods may require an export license — confirmed per order.

Frequently asked questions
How is pricing structured?
Quotes reference the day's silver price on assayed contained metal plus a stated conversion charge, lockable at order confirmation.
Do silver compounds need an export license?
Silver items appear in China's export licensing catalog; whether a specific compound and pack size requires a license depends on classification. We confirm the compliant paperwork per order before shipment.
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.
