Chemical Structure
Description
The occurrence of 2,7-Dibromoanthracen-9(10H)-one is closely related to a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,7-Dibromoanthracen-9(10H)-one (CAS 38917-92-9), molecular formula C14H8Br2O and molecular weight 352.02 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,7-Dibromoanthracen-9(10H)-one (C14H8Br2O) contains a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 352.02 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
