Chemical Structure
Description
Based on its molecular formula C7H3Br2FO, 2,4-Dibromo-5-fluorobenzaldehyde contains 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 281.90 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2,4-Dibromo-5-fluorobenzaldehyde (CAS 1806352-88-4) is a high-purity analytical reference standard with the molecular formula C7H3Br2FO and a molecular weight of 281.90 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.
