Chemical Structure

(3-Bromo-5-ethoxy-4-((4-fluorobenzyl)oxy)phenyl)methanol CAS 1156149-20-0 chemical structure

Description

The occurrence of (3-Bromo-5-ethoxy-4-((4-fluorobenzyl)oxy)phenyl)methanol is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (3-Bromo-5-ethoxy-4-((4-fluorobenzyl)oxy)phenyl)methanol (CAS 1156149-20-0), a certified reference material (molecular formula C16H16BrFO3, MW 355.20 g/mol) for analytical method development and quality control.

(3-Bromo-5-ethoxy-4-((4-fluorobenzyl)oxy)phenyl)methanol (C16H16BrFO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, a polycyclic aromatic system. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

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.
