The occurrence of Sodium antimonate is closely related to an inorganic composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Sodium antimonate (CAS 15432-85-6), a certified reference material (molecular formula O4SbNa, MW 208.75 g/mol) for analytical method development and quality control.
Based on its molecular formula O4SbNa, Sodium antimonate contains an inorganic composition; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 208.75 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
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 antimonate 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.
