Chemical Structure
Description
The molecular framework of (E)-2-(Bis(methylthio)methylene)-5-(furan-2-yl)-3-oxopent-4-enenitrile (C12H11NO2S2) is characterized by a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(E)-2-(Bis(methylthio)methylene)-5-(furan-2-yl)-3-oxopent-4-enenitrile (CAS 64307-23-9) is a high-purity analytical reference standard with the molecular formula C12H11NO2S2 and a molecular weight of 265.35 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
