Chemical Structure
Description
Structurally, 3-[(3-bromophenyl)methyl]-5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazine dihydrochloride (C12H13BrN4HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 329.63 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).
3-[(3-bromophenyl)methyl]-5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazine dihydrochloride (CAS 1798729-90-4), molecular formula C12H13BrN4HCl and molecular weight 329.63 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.
As a certified reference material (CRM), 3-[(3-bromophenyl)methyl]-5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazine dihydrochloride 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.
