Chemical Structure

5,6-Diphenyl-3-(2-pyridyl)-1,2,4-triazine CAS 1046-56-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 310.35 g/mol gives 5,6-Diphenyl-3-(2-pyridyl)-1,2,4-triazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5,6-Diphenyl-3-(2-pyridyl)-1,2,4-triazine (CAS 1046-56-6), molecular formula C20H14N4 and molecular weight 310.35 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5,6-Diphenyl-3-(2-pyridyl)-1,2,4-triazine (C20H14N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 310.35 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 5,6-Diphenyl-3-(2-pyridyl)-1,2,4-triazine 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.
