Dysprosium Nitrate Hexahydrate CAS 35725-30-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Dysprosium Nitrate Hexahydrate.

Dysprosium Nitrate Hexahydrate (CAS 35725-30-5), molecular formula DyHNO3H2O and molecular weight 243.53 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Dysprosium Nitrate Hexahydrate (DyHNO3H2O) contains an inorganic composition. The molecule exhibits a degree of unsaturation (DBE) of 0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 243.53 g/mol, it falls into the medium-molecular-weight range. 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.
