Chemical Structure
Description
2,4,6-Tribromopyridin-3-amine (CAS 84539-49-1), molecular formula C5H3Br3N2 and molecular weight 330.80 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,4,6-Tribromopyridin-3-amine (C5H3Br3N2) contains a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 330.80 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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.
As a certified reference material (CRM), 2,4,6-Tribromopyridin-3-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
