Chemical Structure

Pyridine D5 CAS 7291-22-7 chemical structure

Description

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.

Pyridine D5 (CAS 7291-22-7), molecular formula C5D5N and molecular weight 84.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Pyridine D5 (C5D5N) is characterized by deuterium isotope labeling, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), Pyridine D5 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.
