Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 348.35 g/mol gives 5-Methyl-5H-dibenzo[b,d]thiophen-5-ium trifluoromethanesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Methyl-5H-dibenzo[b,d]thiophen-5-ium trifluoromethanesulfonate (CAS 112359-25-8), molecular formula C13H11SCF3O3S and molecular weight 348.35 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Methyl-5H-dibenzo[b,d]thiophen-5-ium trifluoromethanesulfonate (C13H11SCF3O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 5-Methyl-5H-dibenzo[b,d]thiophen-5-ium trifluoromethanesulfonate 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.
