Chemical Structure
Description
The occurrence of 3-Amino-5-bromo-1,2,4-triazine is closely related to a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Amino-5-bromo-1,2,4-triazine (CAS 1446406-83-2), molecular formula C3H3BrN4 and molecular weight 174.99 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, bromine substitution, 3-Amino-5-bromo-1,2,4-triazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.99 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
