Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromodibenzo[b,e][1,4]dioxine.
2-Bromodibenzo[b,e][1,4]dioxine (CAS 105906-36-3) is a high-purity analytical reference standard with the molecular formula C12H7BrO2 and a molecular weight of 263.09 g/mol.
Based on its molecular formula C12H7BrO2, 2-Bromodibenzo[b,e][1,4]dioxine contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 263.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
