Compared with other compounds in its class, the molecular weight of 264.08 g/mol gives 8-Bromo-5H-[1,2,4]triazino[5,6-b]indol-3-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
8-Bromo-5H-[1,2,4]triazino[5,6-b]indol-3-amine (CAS 910443-21-9), molecular formula C9H6BrN5 and molecular weight 264.08 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 8-Bromo-5H-[1,2,4]triazino[5,6-b]indol-3-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
