Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 3-bromo-5-fluoro-2-isopropoxybenzoate.
CATO supplies Methyl 3-bromo-5-fluoro-2-isopropoxybenzoate (CAS 2119355-79-0), a certified reference material (molecular formula C11H12BrFO3, MW 291.11 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H12BrFO3, Methyl 3-bromo-5-fluoro-2-isopropoxybenzoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 291.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
