Chemical Structure

Dysprosium(III) acetate hydrate CAS 15280-55-4 chemical structure

Description

The occurrence of Dysprosium(III) acetate hydrate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Dysprosium(III) acetate hydrate (CAS 15280-55-4), molecular formula DyC2H3O2 and molecular weight 221.54 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Dysprosium(III) acetate hydrate (DyC2H3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.5, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 221.54 g/mol, it falls into the medium-molecular-weight range.

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.

As a certified reference material (CRM), Dysprosium(III) acetate hydrate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
