Chemical Structure

Diammonium Cerium(IV) Sulfate CAS 7637-03-8 chemical structure

Description

The molecular framework of Diammonium Cerium(IV) Sulfate (CeO4SH4N) is characterized by a sulfone group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies Diammonium Cerium(IV) Sulfate (CAS 7637-03-8), a certified reference material (molecular formula CeO4SH4N, MW 254.22 g/mol) for analytical method development and quality control.

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), Diammonium Cerium(IV) Sulfate 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.
