Ethyl 2,2-dibromo-4,4,4-trifluoro-3-oxobutanoate CAS 382-40-1

Description

The occurrence of Ethyl 2,2-dibromo-4,4,4-trifluoro-3-oxobutanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 2,2-dibromo-4,4,4-trifluoro-3-oxobutanoate (CAS 382-40-1), molecular formula C6H5Br2F3O3 and molecular weight 341.91 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C6H5Br2F3O3, Ethyl 2,2-dibromo-4,4,4-trifluoro-3-oxobutanoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 341.91 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
