Chemical Structure
Description
(5-Fluoro-4-methoxypyrimidin-2-yl)boronic acid (CAS 1161497-29-5), molecular formula C5H6BFN2O3 and molecular weight 171.92 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5H6BFN2O3, (5-Fluoro-4-methoxypyrimidin-2-yl)boronic acid contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 171.92 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.
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.
