Chemical Structure
Description
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.
Chromium(III) sulfate hydrate (CAS 15244-38-9) is a high-purity analytical reference standard with the molecular formula O4SCrH2O and a molecular weight of 166.07 g/mol.
The molecular framework of Chromium(III) sulfate hydrate (O4SCrH2O) is characterized by a sulfone group. 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.
As a certified reference material (CRM), Chromium(III) sulfate 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.
