Chemical Structure
Description
The molecular framework of 2-(Cyclopentylsulfanyl)-5,7-dimethyl-[1,2,4]triazolo[1,5-a]pyrimidine (C12H16N4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
2-(Cyclopentylsulfanyl)-5,7-dimethyl-[1,2,4]triazolo[1,5-a]pyrimidine (CAS 861208-15-3) is a high-purity analytical reference standard with the molecular formula C12H16N4S and a molecular weight of 248.35 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
