Chemical Structure
Description
The occurrence of 5,6,7,8-Tetrahydro-2-(4-pyridinyl)-[1]benzothieno[2,3-d]pyrimidin-4(1H)-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.
5,6,7,8-Tetrahydro-2-(4-pyridinyl)-[1]benzothieno[2,3-d]pyrimidin-4(1H)-one (CAS 357618-22-5) is a high-purity analytical reference standard with the molecular formula C15H13N3OS and a molecular weight of 283.35 g/mol.
The molecular framework of 5,6,7,8-Tetrahydro-2-(4-pyridinyl)-[1]benzothieno[2,3-d]pyrimidin-4(1H)-one (C15H13N3OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
