Chemical Structure
Description
[4-bromo-5-(difluoromethoxy)-6-fluoro-2-naphthyl] 2,2-dimethylpropanoate (CAS 2763159-26-6), molecular formula C16H24BrF3O3 and molecular weight 401.26 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H24BrF3O3, [4-bromo-5-(difluoromethoxy)-6-fluoro-2-naphthyl] 2,2-dimethylpropanoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 401.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
