Diethyl 2,6-bis(methylthio)-4-oxo-4H-thiopyran-3,5-dicarboxylate CAS 13700-78-2

Description

Compared with other compounds in its class, the molecular weight of 260.44 g/mol gives Diethyl 2,6-bis(methylthio)-4-oxo-4H-thiopyran-3,5-dicarboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Diethyl 2,6-bis(methylthio)-4-oxo-4H-thiopyran-3,5-dicarboxylate (CAS 13700-78-2), a certified reference material (molecular formula C11H16OS3, MW 260.44 g/mol) for analytical method development and quality control.

The molecular framework of Diethyl 2,6-bis(methylthio)-4-oxo-4H-thiopyran-3,5-dicarboxylate (C11H16OS3) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
