Compared with other compounds in its class, the molecular weight of 448.91 g/mol gives Sodium hexachloroosmate(IV) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Sodium hexachloroosmate(IV) (CAS 1307-81-9), a certified reference material (molecular formula Cl6OsNa2, MW 448.91 g/mol) for analytical method development and quality control.
Sodium hexachloroosmate(IV) (Cl6OsNa2) contains a salt form, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Sodium hexachloroosmate(IV) 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.
