Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 257.12 g/mol gives 5-Bromo-2-isopropyl-2,3-dihydrobenzofuran-3-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Bromo-2-isopropyl-2,3-dihydrobenzofuran-3-ol (CAS 18968-38-2), molecular formula C11H13BrO2 and molecular weight 257.12 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromo-2-isopropyl-2,3-dihydrobenzofuran-3-ol (C11H13BrO2) 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, 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.
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.
