Chemical Structure
Description
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.
2-Chloro-6-ethyl-N,N-dimethylthieno[2,3-d]pyrimidin-4-amine (CAS 1216082-23-3) is a high-purity analytical reference standard with the molecular formula C10H12ClN3S and a molecular weight of 241.74 g/mol.
2-Chloro-6-ethyl-N,N-dimethylthieno[2,3-d]pyrimidin-4-amine (C10H12ClN3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
