Where K₂PtCl₄ is used
Platinum complex synthesis
The standard entry to Pt(II) chemistry: phosphine, amine and NHC complexes, platinum-based drug research analogues, and luminescent cyclometalated platinum materials all start from K₂PtCl₄.
Surface functionalization and plating
Used in immersion and electroless platinum deposition and in preparing platinized research electrodes where a well-defined ionic Pt(II) source is required.
Storage and shipping
Storage. Store sealed and dry, protected from light; aqueous solutions slowly hydrolyze.
Shipping. Ships by commercial courier with SDS; sensitizer note included for handling.

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.
K₂PtCl₄ or PtCl₂ for complex synthesis?
K₂PtCl₄ dissolves directly in water and reacts under mild conditions, making it the more convenient Pt(II) source; PtCl₂ suits organic-phase routes and carries a higher Pt percentage per gram.
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.
