Chemical Structure
Description
Yttrium(III) phosphate (CAS 13990-54-0), molecular formula O4PY and molecular weight 183.88 g/mol, is a CATO reference standard with documented purity and traceability.
Yttrium(III) phosphate (O4PY) 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.
