Chemical Structure

Cerium(III) chloride heptahydrate CAS 18618-55-8 chemical structure

Description

The occurrence of Cerium(III) chloride heptahydrate is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Cerium(III) chloride heptahydrate (CAS 18618-55-8), molecular formula CeCl3H2O and molecular weight 264.49 g/mol, is a CATO reference standard with documented purity and traceability.

Cerium(III) chloride heptahydrate (CeCl3H2O) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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) chloride heptahydrate 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.
