Chemical Structure
Description
5,6,7-Trimethyl-2-[(2-methylpropyl)sulfanyl]-[1,2,4]triazolo[1,5-a]pyrimidine (C12H18N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
5,6,7-Trimethyl-2-[(2-methylpropyl)sulfanyl]-[1,2,4]triazolo[1,5-a]pyrimidine (CAS 442672-66-4), molecular formula C12H18N4S and molecular weight 250.36 g/mol, is a CATO reference standard with documented purity and traceability.
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.
