Compared with other compounds in its class, the molecular weight of 263.31 g/mol gives Strontium Ferrite distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Strontium Ferrite (CAS 12023-91-5), molecular formula Fe2O3OSr and molecular weight 263.31 g/mol, is a CATO reference standard with documented purity and traceability.
Strontium Ferrite (Fe2O3OSr) 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.
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.
