2-Chlorotetrafluoropropionyl bromide CAS 261503-70-2

Description

Compared with other compounds in its class, the molecular weight of 243.38 g/mol gives 2-Chlorotetrafluoropropionyl bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Chlorotetrafluoropropionyl bromide (CAS 261503-70-2) is a high-purity analytical reference standard with the molecular formula C3BrClF4O and a molecular weight of 243.38 g/mol.

Structurally, 2-Chlorotetrafluoropropionyl bromide (C3BrClF4O) contains 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 243.38 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.

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.
