Diethyl 3,3-difluoropentanedioate CAS 2710-66-9

Description

Compared with other compounds in its class, the molecular weight of 224.20 g/mol gives Diethyl 3,3-difluoropentanedioate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Diethyl 3,3-difluoropentanedioate (CAS 2710-66-9), molecular formula C9H14F2O4 and molecular weight 224.20 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Diethyl 3,3-difluoropentanedioate (C9H14F2O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 224.20 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.

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.
