1,2,4-Triphenylpyridin-1-ium iodide CAS 80576-28-9

Description

The occurrence of 1,2,4-Triphenylpyridin-1-ium iodide is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,2,4-Triphenylpyridin-1-ium iodide (CAS 80576-28-9) is a high-purity analytical reference standard with the molecular formula C23H18NI and a molecular weight of 435.30 g/mol.

Structurally, 1,2,4-Triphenylpyridin-1-ium iodide (C23H18NI) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 435.30 g/mol, it falls into the moderately-high-molecular-weight range. 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.
