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.
5-Chloro-3-((4-chlorophenyl)thio)-2-methyl-1H-indole (CAS 628736-22-1) is a high-purity analytical reference standard with the molecular formula C15H11Cl2NS and a molecular weight of 308.23 g/mol.
The molecular framework of 5-Chloro-3-((4-chlorophenyl)thio)-2-methyl-1H-indole (C15H11Cl2NS) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 5-Chloro-3-((4-chlorophenyl)thio)-2-methyl-1H-indole 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.
