Chemical Structure
Description
The occurrence of Potassium Trifluoro(2-phenylethyl)borate is closely related to fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Potassium Trifluoro(2-phenylethyl)borate (CAS 329976-74-1) is a high-purity analytical reference standard with the molecular formula C8H9BF3K and a molecular weight of 212.06 g/mol.
Based on its molecular formula C8H9BF3K, Potassium Trifluoro(2-phenylethyl)borate contains fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 212.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
