Chemical Structure

Lanthanum(III) oxalate hydrate CAS 312696-10-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 244.94 g/mol gives Lanthanum(III) oxalate hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Lanthanum(III) oxalate hydrate (CAS 312696-10-9) is a high-purity analytical reference standard with the molecular formula LaC2O4H2O and a molecular weight of 244.94 g/mol.

Lanthanum(III) oxalate hydrate (LaC2O4H2O) contains a carboxylic acid group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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), Lanthanum(III) oxalate 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.
