Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,7-Dibromo-10,11-dihydro-5H-dibenzo[a,d][7]annulen-5-one.
3,7-Dibromo-10,11-dihydro-5H-dibenzo[a,d][7]annulen-5-one (CAS 226946-20-9) is a high-purity analytical reference standard with the molecular formula C15H10Br2O and a molecular weight of 366.05 g/mol.
Structurally, 3,7-Dibromo-10,11-dihydro-5H-dibenzo[a,d][7]annulen-5-one (C15H10Br2O) 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 366.05 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
