5-Oxo-2-(thiophen-2-yl)tetrahydrofuran-3-carboxylic acid CAS 1399659-07-4

Description

The occurrence of 5-Oxo-2-(thiophen-2-yl)tetrahydrofuran-3-carboxylic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-Oxo-2-(thiophen-2-yl)tetrahydrofuran-3-carboxylic acid (CAS 1399659-07-4), a certified reference material (molecular formula C9H8O4S, MW 212.22 g/mol) for analytical method development and quality control.

5-Oxo-2-(thiophen-2-yl)tetrahydrofuran-3-carboxylic acid (C9H8O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 5-Oxo-2-(thiophen-2-yl)tetrahydrofuran-3-carboxylic acid 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.
