2-Bromo-1-(7-bromo-9,9-difluoro-9H-fluoren-2-yl)ethanone CAS 1446138-83-5

Description

The occurrence of 2-Bromo-1-(7-bromo-9,9-difluoro-9H-fluoren-2-yl)ethanone is closely related to a hydroxyl group, an ether linkage, fluorine/bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-Bromo-1-(7-bromo-9,9-difluoro-9H-fluoren-2-yl)ethanone (CAS 1446138-83-5), a certified reference material (molecular formula C15H8Br2F2O, MW 402.03 g/mol) for analytical method development and quality control.

2-Bromo-1-(7-bromo-9,9-difluoro-9H-fluoren-2-yl)ethanone (C15H8Br2F2O) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
