Chemical Structure
Description
As a certified reference material (CRM), Potassium trifluoro(thiophen-2-ylmethyl)borate 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.
Potassium trifluoro(thiophen-2-ylmethyl)borate (CAS 888711-49-7) is a high-purity analytical reference standard with the molecular formula C5H5BF3SK and a molecular weight of 204.06 g/mol.
The molecular framework of Potassium trifluoro(thiophen-2-ylmethyl)borate (C5H5BF3SK) is characterized by sulfur-containing functionality, 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.
