Chemical Structure
Description
1-(2,3-Dimethylphenyl)-1H-pyrazolo[3,4-d]pyrimidine-4-thiol (CAS 1082437-01-1) is a high-purity analytical reference standard with the molecular formula C13H12N4S and a molecular weight of 256.33 g/mol.
1-(2,3-Dimethylphenyl)-1H-pyrazolo[3,4-d]pyrimidine-4-thiol (C13H12N4S) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
