Description
As a certified reference material (CRM), (7-Bromo-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)(4-bromophenyl)methanone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
(7-Bromo-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)(4-bromophenyl)methanone (CAS 175136-40-0) is a high-purity analytical reference standard with the molecular formula C15H10Br2O3 and a molecular weight of 398.05 g/mol.
Structurally, (7-Bromo-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)(4-bromophenyl)methanone (C15H10Br2O3) contains a carboxylic acid group, 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 398.05 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.
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.
