Chemical Structure
Description
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.
Methyl 2-bromo-3-[4-(trifluoromethyl)phenyl]propanoate (CAS 1260761-44-1), molecular formula C11H10BrF3O2 and molecular weight 311.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 2-bromo-3-[4-(trifluoromethyl)phenyl]propanoate (C11H10BrF3O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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 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.
