Chemical Structure
Description
CATO supplies 6-Bromo-[1,2,4]triazolo[1,5-a]pyrimidin-7-ol (CAS 56892-17-2), a certified reference material (molecular formula C5H3BrN4O, MW 215.01 g/mol) for analytical method development and quality control.
Based on its molecular formula C5H3BrN4O, 6-Bromo-[1,2,4]triazolo[1,5-a]pyrimidin-7-ol contains an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 215.01 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
