Description
O-(2-Bromoethyl)hydroxylamine hydrobromide (CAS 65920-18-5), molecular formula C2H6BrNOHBr and molecular weight 220.89 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a hydroxyl group, an ether linkage, bromine substitution, O-(2-Bromoethyl)hydroxylamine hydrobromide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 220.89 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), O-(2-Bromoethyl)hydroxylamine hydrobromide 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.
