Chemical Structure

Potassium osmate dihydrate CAS 10022-66-9 chemical structure

Description

The occurrence of Potassium osmate dihydrate is closely related to an inorganic composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Potassium osmate dihydrate (CAS 10022-66-9), molecular formula O4OsKH2O and molecular weight 311.34 g/mol, is a CATO reference standard with documented purity and traceability.

Potassium osmate dihydrate (O4OsKH2O) contains an inorganic composition. It is notably hygroscopic; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Potassium osmate dihydrate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
