Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,4-Dibromophenyl-4'-nitrophenyl ether.
2,4-Dibromophenyl-4'-nitrophenyl ether (CAS 2671-93-4), molecular formula C24H12Br4N2O5 and molecular weight 727.98 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,4-Dibromophenyl-4'-nitrophenyl ether (C24H12Br4N2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 727.98 g/mol, it falls into the high-molecular-weight range. 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.
As a certified reference material (CRM), 2,4-Dibromophenyl-4'-nitrophenyl ether 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.
