Chemical Structure

Cerium(III) hydrogen carbonate pentahydrate CAS 72520-94-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Cerium(III) hydrogen carbonate pentahydrate.

Cerium(III) hydrogen carbonate pentahydrate (CAS 72520-94-6), molecular formula CeCO3H2O and molecular weight 218.14 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Cerium(III) hydrogen carbonate pentahydrate (CeCO3H2O) 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.

As a certified reference material (CRM), Cerium(III) hydrogen carbonate pentahydrate 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.
