Chemical Structure
Description
Potassium 2-fluoro-5-formylphenyltrifluoroborate (CAS 1012868-70-0) is a high-purity analytical reference standard with the molecular formula C7H4BF4OK and a molecular weight of 230.01 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, Potassium 2-fluoro-5-formylphenyltrifluoroborate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 230.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 2-fluoro-5-formylphenyltrifluoroborate 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.
