(4E)-4-[(Thiophen-2-yl)methylidene]-2,3,4,5-tetrahydro-1-benzothiepin-5-one CAS 924275-80-9

Description

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system, (4E)-4-[(Thiophen-2-yl)methylidene]-2,3,4,5-tetrahydro-1-benzothiepin-5-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 272.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

(4E)-4-[(Thiophen-2-yl)methylidene]-2,3,4,5-tetrahydro-1-benzothiepin-5-one (CAS 924275-80-9) is a high-purity analytical reference standard with the molecular formula C15H12OS2 and a molecular weight of 272.39 g/mol.

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.
