(E)-4-(Thiophen-2-yl)but-3-en-2-one CAS 33603-63-3

Description

Based on its molecular formula C8H8OS, (E)-4-(Thiophen-2-yl)but-3-en-2-one contains sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 152.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

(E)-4-(Thiophen-2-yl)but-3-en-2-one (CAS 33603-63-3), molecular formula C8H8OS and molecular weight 152.21 g/mol, is a CATO reference standard with documented purity and traceability.

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.
