Chemical Structure
Description
5-Bromo-2-hydrazinyl-3-nitropyridine (CAS 15862-42-7) is a high-purity analytical reference standard with the molecular formula C5H5BrN4O2 and a molecular weight of 233.02 g/mol.
Structurally, 5-Bromo-2-hydrazinyl-3-nitropyridine (C5H5BrN4O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 233.02 g/mol, it falls into the medium-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-2-hydrazinyl-3-nitropyridine 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.
