Chemical Structure

1-(4-Chlorophenyl)-2,2-difluoroethyl diethyl phosphate CAS 2108663-79-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 328.68 g/mol gives 1-(4-Chlorophenyl)-2,2-difluoroethyl diethyl phosphate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(4-Chlorophenyl)-2,2-difluoroethyl diethyl phosphate (CAS 2108663-79-0) is a high-purity analytical reference standard with the molecular formula C12H16ClF2O4P and a molecular weight of 328.68 g/mol.

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 1-(4-Chlorophenyl)-2,2-difluoroethyl diethyl phosphate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 328.68 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.

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.
