Sodium hexachlororhodate(III) hydrate
CAS 14972-70-4
Sodium hexachlororhodate is the water-stable ionic rhodium source used in plating electrolytes and catalyst manufacture where a fully chloride-coordinated, easily dosed Rh(III) species is preferred over the trichloride.

Frequently asked questions
How is pricing structured?
Quotes reference the day's metal fixing on assayed contained metal plus a stated conversion charge, and can be locked at order confirmation for recurring volumes.
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 — spent catalyst, residues and off-spec lots are assayed on receipt and the recovered metal credited against your next order, closing the loop on your metal inventory.
