CATO supplies 1-Ethyl-4,6-bis(methylthio)-1H-pyrazolo[3,4-d]pyrimidine (CAS 126867-53-6), a certified reference material (molecular formula C9H12N4S2, MW 240.35 g/mol) for analytical method development and quality control.
1-Ethyl-4,6-bis(methylthio)-1H-pyrazolo[3,4-d]pyrimidine (C9H12N4S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
