Dy Standard Solution CAS 7429-91-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 162.50 g/mol gives Dy Standard Solution distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Dy Standard Solution (CAS 7429-91-6) is a high-purity analytical reference standard with the molecular formula Dy and a molecular weight of 162.50 g/mol.

The molecular framework of Dy Standard Solution (Dy) is characterized by an inorganic composition. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
