Chemical Structure
Description
The occurrence of Potassium (5-Methyl-2-furyl)trifluoroborate is closely related to a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Potassium (5-Methyl-2-furyl)trifluoroborate (CAS 1111213-54-7), a certified reference material (molecular formula C5H5BF3OK, MW 188.00 g/mol) for analytical method development and quality control.
Structurally, Potassium (5-Methyl-2-furyl)trifluoroborate (C5H5BF3OK) contains a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 188.00 g/mol, it falls into the medium-molecular-weight range. 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.
