Where AgOTf is used
Catalyst activation and triflate delivery
Activates gold, palladium and rhodium chloride precatalysts to cationic species while installing the weakly coordinating triflate counterion — the most common activator in gold catalysis.
Glycosylation and substitution chemistry
A standard promoter in Koenigs–Knorr-type glycosylations and in converting alkyl halides to triflates for demanding nucleophilic substitutions.

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.
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.
