3-Cyclopentyl-5,6-dimethyl-2-sulfanyl-3h,4h-thieno[2,3-d]pyrimidin-4-one CAS 733031-03-3

Description

The occurrence of 3-Cyclopentyl-5,6-dimethyl-2-sulfanyl-3h,4h-thieno[2,3-d]pyrimidin-4-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Cyclopentyl-5,6-dimethyl-2-sulfanyl-3h,4h-thieno[2,3-d]pyrimidin-4-one (CAS 733031-03-3) is a high-purity analytical reference standard with the molecular formula C13H16N2OS2 and a molecular weight of 280.41 g/mol.

3-Cyclopentyl-5,6-dimethyl-2-sulfanyl-3h,4h-thieno[2,3-d]pyrimidin-4-one (C13H16N2OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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.
