Chemical Structure
Description
5,7-Dimethyl-2-[(2-phenoxyethyl)sulfanyl]-[1,2,4]triazolo[1,5-a]pyrimidine (CAS 866142-71-4) is a high-purity analytical reference standard with the molecular formula C15H16N4OS and a molecular weight of 300.38 g/mol.
The molecular framework of 5,7-Dimethyl-2-[(2-phenoxyethyl)sulfanyl]-[1,2,4]triazolo[1,5-a]pyrimidine (C15H16N4OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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.
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 5,7-Dimethyl-2-[(2-phenoxyethyl)sulfanyl]-[1,2,4]triazolo[1,5-a]pyrimidine 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.
