Europium dibromide CAS 13780-48-8

Description

The occurrence of Europium dibromide is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Europium dibromide (CAS 13780-48-8), a certified reference material (molecular formula Br2Eu, MW 311.77 g/mol) for analytical method development and quality control.

Structurally, Europium dibromide (Br2Eu) contains bromine substitution. 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 311.77 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
