Chemical Structure

4-sulfanylpyridine-3-carbonitrile CAS 1517075-92-1 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.

4-sulfanylpyridine-3-carbonitrile (CAS 1517075-92-1), molecular formula C6H4N2S and molecular weight 136.17 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-sulfanylpyridine-3-carbonitrile (C6H4N2S) is characterized by a nitrile group, sulfur-containing functionality, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 4-sulfanylpyridine-3-carbonitrile 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.
