Chemical Structure

Perfluoroicosane CAS 37589-57-4 chemical structure

Description

Perfluoroicosane (CAS 37589-57-4) is a high-purity analytical reference standard with the molecular formula C20F42 and a molecular weight of 1038.15 g/mol.

Structurally, Perfluoroicosane (C20F42) contains fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 1038.15 g/mol, it falls into the high-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.
