Chemical Structure
Description
(4-(Trifluoromethyl)thiophen-3-yl)methanol (CAS 1881925-70-7) 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 (4-(Trifluoromethyl)thiophen-3-yl)methanol (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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), (4-(Trifluoromethyl)thiophen-3-yl)methanol 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.
