Chemical Structure
Description
5-Bromo-N-(4-chloro-2,5-dimethoxyphenyl)furan-2-carboxamide (CAS 314022-39-4), molecular formula C13H11BrClNO4 and molecular weight 360.59 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Bromo-N-(4-chloro-2,5-dimethoxyphenyl)furan-2-carboxamide (C13H11BrClNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 360.59 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 5-Bromo-N-(4-chloro-2,5-dimethoxyphenyl)furan-2-carboxamide 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.
