Chemical Structure
Description
As a certified reference material (CRM), Tris(2-hydroxyethyl)sulfonium 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.
CATO supplies Tris(2-hydroxyethyl)sulfonium chloride (CAS 869-51-2), a certified reference material (molecular formula C6H15O3SCl, MW 202.69 g/mol) for analytical method development and quality control.
The molecular framework of Tris(2-hydroxyethyl)sulfonium chloride (C6H15O3SCl) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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.
