Description

CATO manufactures 2-((3-Allyl-6-ethyl-4-oxo-3,4-dihydrothieno[2,3-d]pyrimidin-2-yl)thio)-N-cyclohexylacetamide 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.

2-((3-Allyl-6-ethyl-4-oxo-3,4-dihydrothieno[2,3-d]pyrimidin-2-yl)thio)-N-cyclohexylacetamide (CAS 750618-18-9) is a high-purity analytical reference standard with the molecular formula C19H25N3O2S2 and a molecular weight of 391.55 g/mol.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-((3-Allyl-6-ethyl-4-oxo-3,4-dihydrothieno[2,3-d]pyrimidin-2-yl)thio)-N-cyclohexylacetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 391.55 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.
