Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 295.53 g/mol gives 2-(4-Bromo-2-fluorophenoxy)butanoyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-(4-Bromo-2-fluorophenoxy)butanoyl chloride (CAS 2138016-81-4), a certified reference material (molecular formula C10H9BrClFO2, MW 295.53 g/mol) for analytical method development and quality control.
The molecular framework of 2-(4-Bromo-2-fluorophenoxy)butanoyl chloride (C10H9BrClFO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
