Ethyl 4,4-Difluoropentanoate CAS 659-72-3

Description

Compared with other compounds in its class, the molecular weight of 166.17 g/mol gives Ethyl 4,4-Difluoropentanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ethyl 4,4-Difluoropentanoate (CAS 659-72-3), a certified reference material (molecular formula C7H12F2O2, MW 166.17 g/mol) for analytical method development and quality control.

Structurally, Ethyl 4,4-Difluoropentanoate (C7H12F2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 166.17 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
