Chemical Structure
Description
As a certified reference material (CRM), 6-((2,5-Dichlorophenyl)thio)pyridin-3-amine 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.
6-((2,5-Dichlorophenyl)thio)pyridin-3-amine (CAS 219865-85-7), molecular formula C11H8Cl2N2S and molecular weight 271.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-((2,5-Dichlorophenyl)thio)pyridin-3-amine (C11H8Cl2N2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
