Chemical Structure

Lanthanum Carbonate CAS 54451-24-0 chemical structure

Description

Lanthanum Carbonate (CAS 54451-24-0), molecular formula LaCO3 and molecular weight 198.92 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Lanthanum Carbonate (LaCO3) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
