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.

3-phenyl-2-sulfanyl-5-(thiophen-2-yl)-3H,4H-thieno[2,3-d]pyrimidin-4-one (CAS 327167-86-2) is a high-purity analytical reference standard with the molecular formula C16H26N2OS3 and a molecular weight of 358.59 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 3-phenyl-2-sulfanyl-5-(thiophen-2-yl)-3H,4H-thieno[2,3-d]pyrimidin-4-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 358.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
