Description
As a certified reference material (CRM), 2,2,2-Trifluoro-1-(2-thienyl)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.
2,2,2-Trifluoro-1-(2-thienyl)ethanol (CAS 35304-68-8) is a high-purity analytical reference standard with the molecular formula C6H5F3OS and a molecular weight of 182.16 g/mol.
The molecular framework of 2,2,2-Trifluoro-1-(2-thienyl)ethanol (C6H5F3OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine 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. 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).
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.
