Compared with other compounds in its class, the molecular weight of 482.60 g/mol gives Erbium(III) acetylacetonate hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Erbium(III) acetylacetonate hydrate (CAS 81240-87-1), a certified reference material (molecular formula C15H21ErO6H2O, MW 482.60 g/mol) for analytical method development and quality control.
Based on its molecular formula C15H21ErO6H2O, Erbium(III) acetylacetonate hydrate contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 482.60 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
