Description

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.

2-Mercapto-5-(4-methoxyphenyl)-3-phenylthieno[2,3-d]pyrimidin-4(3H)-one (CAS 296899-20-2), molecular formula C19H14N2O2S2 and molecular weight 366.46 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-Mercapto-5-(4-methoxyphenyl)-3-phenylthieno[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 366.46 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).

CATO manufactures 2-Mercapto-5-(4-methoxyphenyl)-3-phenylthieno[2,3-d]pyrimidin-4(3H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation.
