Chemical Structure
Description
N-(4-Bromobenzyl)hydroxylamine (CAS 83670-49-9), molecular formula C7H8BrNO and molecular weight 202.05 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(4-Bromobenzyl)hydroxylamine (C7H8BrNO) is characterized by an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), N-(4-Bromobenzyl)hydroxylamine 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.
