4,4,4-Trifluoro-1-(thiophen-2-yl)butane-1,3-dione CAS 326-91-1

Description

The occurrence of 4,4,4-Trifluoro-1-(thiophen-2-yl)butane-1,3-dione is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4,4,4-Trifluoro-1-(thiophen-2-yl)butane-1,3-dione (CAS 326-91-1), molecular formula C8H5F3O2S and molecular weight 222.18 g/mol, is a CATO reference standard with documented purity and traceability.

4,4,4-Trifluoro-1-(thiophen-2-yl)butane-1,3-dione (C8H5F3O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, 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), 4,4,4-Trifluoro-1-(thiophen-2-yl)butane-1,3-dione 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.
