Chemical Structure

3-Fluoropropanoic anhydride CAS 2266-47-9 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 3-Fluoropropanoic anhydride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

3-Fluoropropanoic anhydride (CAS 2266-47-9) is a high-purity analytical reference standard with the molecular formula C6H8F2O3 and a molecular weight of 166.12 g/mol.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
