Description

Compared with other compounds in its class, the molecular weight of 398.47 g/mol gives 3-Ethyl-5,6-dimethyl-2-((3-(trifluoromethyl)benzyl)thio)thieno[2,3-d]pyrimidin-4(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-Ethyl-5,6-dimethyl-2-((3-(trifluoromethyl)benzyl)thio)thieno[2,3-d]pyrimidin-4(3H)-one (CAS 618427-78-4), a certified reference material (molecular formula C18H17F3N2OS2, MW 398.47 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, 3-Ethyl-5,6-dimethyl-2-((3-(trifluoromethyl)benzyl)thio)thieno[2,3-d]pyrimidin-4(3H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 398.47 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 3-Ethyl-5,6-dimethyl-2-((3-(trifluoromethyl)benzyl)thio)thieno[2,3-d]pyrimidin-4(3H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
