Chemical Structure
Description
2-(Bromomethyl)-5-chloro-2,3-dihydrobenzofuran (CAS 19997-50-3), molecular formula C9H8BrClO and molecular weight 247.52 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(Bromomethyl)-5-chloro-2,3-dihydrobenzofuran (C9H8BrClO) is characterized by a hydroxyl group, an ether linkage, chlorine/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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
