Sodium hexachloroplatinate(IV) hexahydrate, CAS 19583-77-8

Sodium hexachloroplatinate(IV) hexahydrate Na₂PtCl₆·6H₂O, a complex platinum(IV) salt, CAS 19583-77-8

Substance identification

CAS 19583-77-8 and formula Na₂PtCl₆·6H₂O identify sodium hexachloroplatinate(IV) hexahydrate. Platinum is in the +4 oxidation state, and six water molecules are part of the crystalline form. The calculated Pt content of about 34.72% is consistent with the initial requirement of not less than 34.5%; the actual value is confirmed by the batch CoA.

Confirmed specifications

• CAS: 19583-77-8
• Formula: Na₂PtCl₆·6H₂O
• Molar mass: about 561.9 g/mol
• Platinum: not less than 34.5% per TU 6-09-1918-72
• Item number: 5162684

Applications and preparation

The salt is used as a laboratory platinum precursor for preparing complexes, catalytic and electrochemical materials according to specific procedures. The hexahydrate cannot be replaced without recalculation by the anhydrous form or another chloroplatinate salt. The result depends on acidity, chloride environment, water, and impurities, so this datasheet does not define a finished formulation.

The sample weight is calculated based on the molar mass of the hexahydrate and the Pt analysis. Solutions are prepared in compatible glassware under controlled acidity; the opened product is protected from contamination and changes in hydration. For quantitative calibration, a certified standard with traceability is required, not just a reagent with a specified metal content.

What to confirm before ordering

Request the CoA and SDS with CAS 19583-77-8, Na₂PtCl₆·6H₂O, Pt content, water, sodium, and impurity metals. Clarify appearance, analytical method, pack size, and storage. For synthesis, specify allowable impurities and required acidity; for sensitive electrochemistry, residual organic substances and insoluble residue.

Safe handling

Soluble platinum salts may cause irritation and sensitization. Work in a fume hood, avoiding dust and aerosol, and use safety glasses, lab coat, and gloves per the SDS. Avoid skin contact and cross-contamination. Collect spills, solutions, washings, and containers separately as platinum-containing hazardous waste.
