Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Potassium trifluoro(4-methoxy-2-methylphenyl)borate.
CATO supplies Potassium trifluoro(4-methoxy-2-methylphenyl)borate (CAS 850623-69-7), a certified reference material (molecular formula C8H9BF3OK, MW 228.06 g/mol) for analytical method development and quality control.
Potassium trifluoro(4-methoxy-2-methylphenyl)borate (C8H9BF3OK) contains a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
