Chemical Structure

3-(3-Methylbutyl)-2-sulfanyl-5-(thiophen-2-yl)-3h,4h-thieno[2,3-d]pyrimidin-4-one CAS 731827-19-3 chemical structure

Description

3-(3-Methylbutyl)-2-sulfanyl-5-(thiophen-2-yl)-3h,4h-thieno[2,3-d]pyrimidin-4-one (CAS 731827-19-3) is a high-purity analytical reference standard with the molecular formula C15H16N2OS3 and a molecular weight of 336.50 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 3-(3-Methylbutyl)-2-sulfanyl-5-(thiophen-2-yl)-3h,4h-thieno[2,3-d]pyrimidin-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 336.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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-(3-Methylbutyl)-2-sulfanyl-5-(thiophen-2-yl)-3h,4h-thieno[2,3-d]pyrimidin-4-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.
