Chemical Structure

Ethyl 3-bromo-5-ethoxy-4-((4-fluorobenzyl)oxy)benzoate CAS 1706447-31-5 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO supplies Ethyl 3-bromo-5-ethoxy-4-((4-fluorobenzyl)oxy)benzoate (CAS 1706447-31-5), a certified reference material (molecular formula C18H18BrFO4, MW 397.24 g/mol) for analytical method development and quality control.

Ethyl 3-bromo-5-ethoxy-4-((4-fluorobenzyl)oxy)benzoate (C18H18BrFO4) contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures Ethyl 3-bromo-5-ethoxy-4-((4-fluorobenzyl)oxy)benzoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
