3-((2,4-Dichlorobenzyl)thio)-5-propyl-[1,2,4]triazolo[4,3-a]pyrimidin-7(8H)-one (CAS 891127-55-2) is a high-purity analytical reference standard with the molecular formula C15H14Cl2N4OS and a molecular weight of 369.27 g/mol.
The molecular framework of 3-((2,4-Dichlorobenzyl)thio)-5-propyl-[1,2,4]triazolo[4,3-a]pyrimidin-7(8H)-one (C15H14Cl2N4OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
