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 1,3-Dibromoanthracene-9,10-dione (CAS 602-72-2), a certified reference material (molecular formula C14H6Br2O2, MW 366.00 g/mol) for analytical method development and quality control.
Based on its molecular formula C14H6Br2O2, 1,3-Dibromoanthracene-9,10-dione contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 366.00 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.
