Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 270.08 g/mol gives N-(4-Bromophenyl)maleamic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-(4-Bromophenyl)maleamic acid (CAS 59256-47-2) is a high-purity analytical reference standard with the molecular formula C10H8BrNO3 and a molecular weight of 270.08 g/mol.
Structurally, N-(4-Bromophenyl)maleamic acid (C10H8BrNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 270.08 g/mol, it falls into the medium-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), N-(4-Bromophenyl)maleamic acid 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.
