Chemical Structure

3-(2,2-Difluoroethyl)pyrrolidine CAS 1566754-28-6 chemical structure

Description

3-(2,2-Difluoroethyl)pyrrolidine (CAS 1566754-28-6), molecular formula C6H11F2N and molecular weight 135.16 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to fluorine substitution, 3-(2,2-Difluoroethyl)pyrrolidine is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 135.16 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.
