Chemical Structure
Description
As a certified reference material (CRM), 3-Acetyl-3-fluorodihydrofuran-2(3H)-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.
3-Acetyl-3-fluorodihydrofuran-2(3H)-one (CAS 63141-03-7) is a high-purity analytical reference standard with the molecular formula C6H7FO3 and a molecular weight of 146.12 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 3-Acetyl-3-fluorodihydrofuran-2(3H)-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
