Chemical Structure
Description
1-Azido-2-bromoethane (CAS 19263-22-0) is a high-purity analytical reference standard with the molecular formula C2H4BrN3 and a molecular weight of 149.98 g/mol.
Based on its molecular formula C2H4BrN3, 1-Azido-2-bromoethane contains a nitrile group, bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 149.98 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 1-Azido-2-bromoethane 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.
