Description
The occurrence of N-(2,4-Dimethylphenyl)-2-((3-(4-methoxyphenyl)-4-oxo-3,4,5,6,7,8-hexahydrobenzo[4,5]thieno[2,3-d]pyrimidin-2-yl)thio)acetamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(2,4-Dimethylphenyl)-2-((3-(4-methoxyphenyl)-4-oxo-3,4,5,6,7,8-hexahydrobenzo[4,5]thieno[2,3-d]pyrimidin-2-yl)thio)acetamide (CAS 476485-68-4) is a high-purity analytical reference standard with the molecular formula C27H27N3O3S2 and a molecular weight of 505.65 g/mol.
The molecular framework of N-(2,4-Dimethylphenyl)-2-((3-(4-methoxyphenyl)-4-oxo-3,4,5,6,7,8-hexahydrobenzo[4,5]thieno[2,3-d]pyrimidin-2-yl)thio)acetamide (C27H27N3O3S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
