Chemical Structure
Description
Owing to an amide group, a hydroxyl group, an ether linkage, bromine substitution, 3-Amino-6-bromo-1,2,4-triazin-5(4H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 190.99 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
3-Amino-6-bromo-1,2,4-triazin-5(4H)-one (CAS 70481-87-7), molecular formula C3H3BrN4O and molecular weight 190.99 g/mol, is a CATO reference standard with documented purity and traceability.
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.
