Compared with other compounds in its class, the molecular weight of 298.83 g/mol gives Triphenylsulfonium chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Triphenylsulfonium chloride (CAS 4270-70-6), a certified reference material (molecular formula C18H15SCl, MW 298.83 g/mol) for analytical method development and quality control.
Based on its molecular formula C18H15SCl, Triphenylsulfonium chloride contains sulfur-containing functionality, chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 298.83 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Triphenylsulfonium 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.
