6,8-Dibromo-2-(2-((tert-butyldimethylsilyl)oxy)ethyl)-5-methyl-[1,2,4]triazolo[1,5-a]pyrazine (CAS 2428557-56-4) is a high-purity analytical reference standard with the molecular formula C14H22Br2N4OSi and a molecular weight of 450.24 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 6,8-Dibromo-2-(2-((tert-butyldimethylsilyl)oxy)ethyl)-5-methyl-[1,2,4]triazolo[1,5-a]pyrazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 450.24 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.
