Chemical Structure
Description
Iron(III) phosphate hydrate (CAS 51833-68-2), molecular formula H3O4PFeH2O and molecular weight 171.85 g/mol, is a CATO reference standard with documented purity and traceability.
Iron(III) phosphate hydrate (H3O4PFeH2O) contains a phosphate ester group. 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.
