Chemical Structure
Description
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.
CATO supplies 7-Bromo-9,9,9',9'-tetraethyl-2,2'-bifluorene (CAS 862847-75-4), a certified reference material (molecular formula C34H33Br, MW 521.53 g/mol) for analytical method development and quality control.
Based on its molecular formula C34H33Br, 7-Bromo-9,9,9',9'-tetraethyl-2,2'-bifluorene contains bromine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 521.53 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
