Description
As a certified reference material (CRM), N-(2-Bromophenyl)-2-nitrobenzamide 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.
N-(2-Bromophenyl)-2-nitrobenzamide (CAS 34489-84-4) is a high-purity analytical reference standard with the molecular formula C13H9BrN2O3 and a molecular weight of 321.13 g/mol.
Structurally, N-(2-Bromophenyl)-2-nitrobenzamide (C13H9BrN2O3) 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 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 321.13 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
