Methyl 2-((2-(methylthio)benzo[4,5]thieno[3,2-d]pyrimidin-4-yl)thio)benzoate CAS 478029-96-8

Description

Methyl 2-((2-(methylthio)benzo[4,5]thieno[3,2-d]pyrimidin-4-yl)thio)benzoate (CAS 478029-96-8) is a high-purity analytical reference standard with the molecular formula C19H14N2O2S3 and a molecular weight of 398.52 g/mol.

The molecular framework of Methyl 2-((2-(methylthio)benzo[4,5]thieno[3,2-d]pyrimidin-4-yl)thio)benzoate (C19H14N2O2S3) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
