Chemical Structure

Lanthanum(III) bromide heptahydrate (99.9%-La) (REO) CAS 13465-19-5 chemical structure

Description

Lanthanum(III) bromide heptahydrate (99.9%-La) (REO) (CAS 13465-19-5) is a high-purity analytical reference standard with the molecular formula Br3LaH2O and a molecular weight of 396.64 g/mol.

Based on its molecular formula Br3LaH2O, Lanthanum(III) bromide heptahydrate (99.9%-La) (REO) contains bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 396.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
