3,4,6-Trichloro-1H-pyrrolo[2,3-b]pyridine (CAS 2452251-85-1) is a high-purity analytical reference standard with the molecular formula C7H3Cl3N2 and a molecular weight of 221.47 g/mol.
The molecular framework of 3,4,6-Trichloro-1H-pyrrolo[2,3-b]pyridine (C7H3Cl3N2) is characterized by a nitrile group, chlorine substitution, an aromatic ring system. 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).
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.
