Chemical Structure

(E)-1,3-Di(thiophen-2-yl)prop-2-en-1-one CAS 42811-88-1 chemical structure

Description

The molecular framework of (E)-1,3-Di(thiophen-2-yl)prop-2-en-1-one (C11H8OS2) 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.

(E)-1,3-Di(thiophen-2-yl)prop-2-en-1-one (CAS 42811-88-1) is a high-purity analytical reference standard with the molecular formula C11H8OS2 and a molecular weight of 220.31 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.
