Chemical Structure

1-Chloro-4,4-difluoropentane CAS 406-80-4 chemical structure

Description

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.

1-Chloro-4,4-difluoropentane (CAS 406-80-4) is a high-purity analytical reference standard with the molecular formula C5H9ClF2 and a molecular weight of 142.57 g/mol.

Owing to fluorine/chlorine substitution, 1-Chloro-4,4-difluoropentane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 142.57 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.

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.
