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.
Ethyl 2,3-dibromo-4,6-difluorophenylacetate (CAS 1803783-42-7) is a high-purity analytical reference standard with the molecular formula C10H8Br2F2O2 and a molecular weight of 357.97 g/mol.
Based on its molecular formula C10H8Br2F2O2, Ethyl 2,3-dibromo-4,6-difluorophenylacetate contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 357.97 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.
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.
