Chemical Structure

3-Bromo-4-chloro-2,2,3,4,4-pentafluorobutanoic acid CAS 216393-99-6 chemical structure

Description

Structurally, 3-Bromo-4-chloro-2,2,3,4,4-pentafluorobutanoic acid (C4HBrClF5O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 291.40 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.

3-Bromo-4-chloro-2,2,3,4,4-pentafluorobutanoic acid (CAS 216393-99-6) is a high-purity analytical reference standard with the molecular formula C4HBrClF5O2 and a molecular weight of 291.40 g/mol.

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.
