Chemical Structure
Description
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.
6-(4-Chlorophenyl)-2,3-diphenylimidazo[1,2-b][1,2,4]triazine (CAS 58431-82-6), molecular formula C23H15ClN4 and molecular weight 382.85 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 6-(4-Chlorophenyl)-2,3-diphenylimidazo[1,2-b][1,2,4]triazine (C23H15ClN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 382.85 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
