Chemical Structure

2H-Nonafluorobutane CAS 680-17-1 chemical structure

Description

The occurrence of 2H-Nonafluorobutane is closely related to fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2H-Nonafluorobutane (CAS 680-17-1) is a high-purity analytical reference standard with the molecular formula C4HF9 and a molecular weight of 220.04 g/mol.

Owing to fluorine substitution, 2H-Nonafluorobutane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 220.04 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.
