Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 384.02 g/mol gives 3-(3,5-Dibromo-4-hydroxyphenyl)isobenzofuran-1(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(3,5-Dibromo-4-hydroxyphenyl)isobenzofuran-1(3H)-one (CAS 6315-30-6) is a high-purity analytical reference standard with the molecular formula C14H8Br2O3 and a molecular weight of 384.02 g/mol.
3-(3,5-Dibromo-4-hydroxyphenyl)isobenzofuran-1(3H)-one (C14H8Br2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
