Chemical Structure
Description
2,8-Bis(methylthio)dibenzo[b,d]furan (CAS 87964-68-9) is a high-purity analytical reference standard with the molecular formula C14H12OS2 and a molecular weight of 260.37 g/mol.
The molecular framework of 2,8-Bis(methylthio)dibenzo[b,d]furan (C14H12OS2) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic 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.
