Compared with other compounds in its class, the molecular weight of 185.62 g/mol gives Strontium hydrogen phosphate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Strontium hydrogen phosphate (CAS 13450-99-2) is a high-purity analytical reference standard with the molecular formula H3O4PSr and a molecular weight of 185.62 g/mol.
Based on its molecular formula H3O4PSr, Strontium hydrogen phosphate contains a phosphate ester group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 185.62 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.
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.
