Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 238.06 g/mol gives Potassium trifluoro((4-methoxyphenyl)ethynyl)borate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Potassium trifluoro((4-methoxyphenyl)ethynyl)borate (CAS 877402-26-1), a certified reference material (molecular formula C9H7BF3OK, MW 238.06 g/mol) for analytical method development and quality control.
The molecular framework of Potassium trifluoro((4-methoxyphenyl)ethynyl)borate (C9H7BF3OK) is characterized by a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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.
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.
