Chemical Structure
Description
CATO supplies 5-bromo-3-ethyl-1-benZofuran-2-carboxylic acid (CAS 86793-66-0), a certified reference material (molecular formula C11H9BrO3, MW 269.09 g/mol) for analytical method development and quality control.
The molecular framework of 5-bromo-3-ethyl-1-benZofuran-2-carboxylic acid (C11H9BrO3) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
