Chemical Structure
Description
The occurrence of Potassium (4-bromostyryl)trifluoroborate is closely related to a salt form, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Potassium (4-bromostyryl)trifluoroborate (CAS 1041465-92-2), molecular formula C8H6BBrF3K and molecular weight 288.94 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H6BBrF3K, Potassium (4-bromostyryl)trifluoroborate contains a salt form, fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 288.94 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
