Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Palladium(II) sulfate (CAS 13566-03-5), molecular formula PdO4S and molecular weight 202.48 g/mol, is a CATO reference standard with documented purity and traceability.
Palladium(II) sulfate (PdO4S) contains a sulfone group. It is notably hygroscopic; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
