Chemical Structure
Description
3-(3,5-Dibromophenyl)propanoic acid (C9H8Br2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
3-(3,5-Dibromophenyl)propanoic acid (CAS 923977-15-5) is a high-purity analytical reference standard with the molecular formula C9H8Br2O2 and a molecular weight of 307.97 g/mol.
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.
