Chemical Structure
Description
The occurrence of Ethyl 3,5-dibromo-2-hydroxybenzoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 3,5-dibromo-2-hydroxybenzoate (CAS 64831-28-3) is a high-purity analytical reference standard with the molecular formula C9H8Br2O3 and a molecular weight of 323.97 g/mol.
The molecular framework of Ethyl 3,5-dibromo-2-hydroxybenzoate (C9H8Br2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
