Chemical Structure
Description
As a certified reference material (CRM), (1S)-1-(2,5-Difluorophenyl)ethan-1-ol 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.
(1S)-1-(2,5-Difluorophenyl)ethan-1-ol (CAS 126534-36-9), molecular formula C8H8F2O and molecular weight 158.15 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1S)-1-(2,5-Difluorophenyl)ethan-1-ol (C8H8F2O) is characterized by 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).
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.
