Chemical Structure

4-(Thiophen-2-yl)but-3-en-2-one CAS 874-83-9 chemical structure

Description

As a certified reference material (CRM), 4-(Thiophen-2-yl)but-3-en-2-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

4-(Thiophen-2-yl)but-3-en-2-one (CAS 874-83-9), molecular formula C8H8OS and molecular weight 152.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-(Thiophen-2-yl)but-3-en-2-one (C8H8OS) 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 the polarity and ionization state of its functional groups, 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).

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.
