Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Yttrium(III) perchlorate, 50% aqueous solution (99.9%-Y) (REO).
Yttrium(III) perchlorate, 50% aqueous solution (99.9%-Y) (REO) (CAS 14017-56-2), molecular formula ClO4YH2O and molecular weight 206.37 g/mol, is a CATO reference standard with documented purity and traceability.
Yttrium(III) perchlorate, 50% aqueous solution (99.9%-Y) (REO) (ClO4YH2O) contains chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
