Chemical Structure

Selenium tetrachloride CAS 10026-03-6 chemical structure

Description

The occurrence of Selenium tetrachloride is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Selenium tetrachloride (CAS 10026-03-6), a certified reference material (molecular formula Cl4Se, MW 220.77 g/mol) for analytical method development and quality control.

Selenium tetrachloride (Cl4Se) 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), Selenium tetrachloride 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.
