Dysprosium(III) nitrate hydrate CAS 100641-13-2 chemical structure

Description

Dysprosium(III) nitrate hydrate (CAS 100641-13-2) is a high-purity analytical reference standard with the molecular formula DyNO3H2O and a molecular weight of 242.52 g/mol.

Owing to an inorganic composition, Dysprosium(III) nitrate hydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 242.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
