Chemical Structure
Description
The occurrence of Potassium 3,4-dibromo-2-thienyltrifluoroborate is closely related to a salt form, sulfur-containing functionality, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Potassium 3,4-dibromo-2-thienyltrifluoroborate (CAS 1401522-75-5), molecular formula C4HBBr2F3SK and molecular weight 347.82 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Potassium 3,4-dibromo-2-thienyltrifluoroborate (C4HBBr2F3SK) is characterized by a salt form, sulfur-containing functionality, fluorine/bromine 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), Potassium 3,4-dibromo-2-thienyltrifluoroborate 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.
