Ethyl 2-(3-bromo-4-hydroxy-5-methoxyphenyl)acetate CAS 1258845-38-3

Description

The occurrence of Ethyl 2-(3-bromo-4-hydroxy-5-methoxyphenyl)acetate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Ethyl 2-(3-bromo-4-hydroxy-5-methoxyphenyl)acetate (CAS 1258845-38-3), a certified reference material (molecular formula C11H13BrO4, MW 289.12 g/mol) for analytical method development and quality control.

Ethyl 2-(3-bromo-4-hydroxy-5-methoxyphenyl)acetate (C11H13BrO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. It is notably hygroscopic, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
