Chemical Structure

4-(1H-pyrrol-3-yl)pyridine CAS 76304-56-8 chemical structure

Description

4-(1H-pyrrol-3-yl)pyridine (CAS 76304-56-8), molecular formula C9H8N2 and molecular weight 144.17 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-(1H-pyrrol-3-yl)pyridine (C9H8N2) 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).

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), 4-(1H-pyrrol-3-yl)pyridine 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.
