Lanthanum(III) Sulfate Hydrate CAS 57804-25-8 chemical structure

Description

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

Lanthanum(III) Sulfate Hydrate (CAS 57804-25-8), molecular formula LaO4SH2O and molecular weight 252.98 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula LaO4SH2O, Lanthanum(III) Sulfate Hydrate contains a sulfone group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 252.98 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
