The molecular framework of 6-(4-Chlorophenyl)-2-{[(2,6-dichlorophenyl)methyl]sulfanyl}-[1,2,4]triazolo[1,5-a]pyrimidin-7-amine (C18H12Cl3N5S) 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 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).
CATO supplies 6-(4-Chlorophenyl)-2-{[(2,6-dichlorophenyl)methyl]sulfanyl}-[1,2,4]triazolo[1,5-a]pyrimidin-7-amine (CAS 338403-85-3), a certified reference material (molecular formula C18H12Cl3N5S, MW 436.75 g/mol) for analytical method development and quality control.
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.
CATO manufactures 6-(4-Chlorophenyl)-2-{[(2,6-dichlorophenyl)methyl]sulfanyl}-[1,2,4]triazolo[1,5-a]pyrimidin-7-amine 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.
