63026-01-7 8571AF EuN3O9.5H2O Europium(III) nitrate pentahydrate CAS 63026-01-7 chemical structure

Description

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.

63026-01-7 8571AF EuN3O9.5H2O Europium(III) nitrate pentahydrate (CAS 63026-01-7) is a high-purity analytical reference standard with the molecular formula EuNO3H2O and a molecular weight of 231.98 g/mol.

63026-01-7 8571AF EuN3O9.5H2O Europium(III) nitrate pentahydrate (EuNO3H2O) contains an inorganic composition. It is notably hygroscopic; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
