1-(3,4-dihydro-2H-pyran-5-yl)-2,2-difluoroethan-1-one (CAS 1564797-97-2) is a high-purity analytical reference standard with the molecular formula C7H8F2O2 and a molecular weight of 162.13 g/mol.

Structurally, 1-(3,4-dihydro-2H-pyran-5-yl)-2,2-difluoroethan-1-one (C7H8F2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 162.13 g/mol, it falls into the medium-molecular-weight range. 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.

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.
