Chemical Structure
Description
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.
CATO supplies 3-(4-Fluoronaphthalen-1-yl)-3-methylisobenzofuran-1(3H)-one (CAS 2968-71-0), a certified reference material (molecular formula C23H16Br4O4, MW 675.99 g/mol) for analytical method development and quality control.
Based on its molecular formula C23H16Br4O4, 3-(4-Fluoronaphthalen-1-yl)-3-methylisobenzofuran-1(3H)-one contains a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 675.99 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.
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.
