Chemical Structure
Description
As a certified reference material (CRM), Selenium(I) chloride 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.
Selenium(I) chloride (CAS 10025-68-0) is a high-purity analytical reference standard with the molecular formula Cl2Se2 and a molecular weight of 228.83 g/mol.
The molecular framework of Selenium(I) chloride (Cl2Se2) is characterized by chlorine substitution. 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. 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.
