2-({3-ethyl-4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-2-yl}sulfanyl)-N-(2-methoxy-5-methylphenyl)acetamide CAS 1040682-82-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-({3-ethyl-4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-2-yl}sulfanyl)-N-(2-methoxy-5-methylphenyl)acetamide.

2-({3-ethyl-4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-2-yl}sulfanyl)-N-(2-methoxy-5-methylphenyl)acetamide (CAS 1040682-82-3), molecular formula C24H23N3O3S2 and molecular weight 465.59 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-({3-ethyl-4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-2-yl}sulfanyl)-N-(2-methoxy-5-methylphenyl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 465.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
