Chemical Structure
Description
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.
2-{[3-(Trifluoromethyl)phenyl]sulfonyl}ethanol (CAS 548739-95-3), molecular formula C9H9F3O3S and molecular weight 254.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-{[3-(Trifluoromethyl)phenyl]sulfonyl}ethanol (C9H9F3O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 2-{[3-(Trifluoromethyl)phenyl]sulfonyl}ethanol 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.
