Chemical Structure
Description
As a certified reference material (CRM), 5-Bromomethyl-4,5-dihydro-oxazol-2-ylaminehydrobromide 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.
5-Bromomethyl-4,5-dihydro-oxazol-2-ylaminehydrobromide (CAS 54377-65-0) is a high-purity analytical reference standard with the molecular formula C4H7BrN2OHBr and a molecular weight of 259.93 g/mol.
The molecular framework of 5-Bromomethyl-4,5-dihydro-oxazol-2-ylaminehydrobromide (C4H7BrN2OHBr) is characterized by an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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. 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.
