Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 172.03 g/mol gives 3,3,4,4-Tetrafluorodihydrofuran-2,5-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3,3,4,4-Tetrafluorodihydrofuran-2,5-dione (CAS 699-30-9), a certified reference material (molecular formula C4F4O3, MW 172.03 g/mol) for analytical method development and quality control.
The molecular framework of 3,3,4,4-Tetrafluorodihydrofuran-2,5-dione (C4F4O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 3,3,4,4-Tetrafluorodihydrofuran-2,5-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.
