Chemical Structure

1,5-Naphthyridine-4-thiol CAS 79425-89-1 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.

1,5-Naphthyridine-4-thiol (CAS 79425-89-1), molecular formula C8H6N2S and molecular weight 162.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,5-Naphthyridine-4-thiol (C8H6N2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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.

CATO manufactures 1,5-Naphthyridine-4-thiol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
