Chemical Structure

3-(1H-Pyrazol-3-yl)pyridine CAS 45887-08-9 chemical structure

Description

The molecular framework of 3-(1H-Pyrazol-3-yl)pyridine (C8H7N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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-(1H-Pyrazol-3-yl)pyridine (CAS 45887-08-9) is a high-purity analytical reference standard with the molecular formula C8H7N3 and a molecular weight of 145.16 g/mol.

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.
