Chemical Structure
Description
The occurrence of methyl 4-(4-bromo-2-fluorophenoxy)butanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
methyl 4-(4-bromo-2-fluorophenoxy)butanoate (CAS 1096852-55-9), molecular formula C11H12BrFO3 and molecular weight 291.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of methyl 4-(4-bromo-2-fluorophenoxy)butanoate (C11H12BrFO3) 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. 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.
As a certified reference material (CRM), methyl 4-(4-bromo-2-fluorophenoxy)butanoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
