3-bromo-4-oxo-pentanoic acid ethyl ester CAS 54260-84-3

Description

The occurrence of 3-bromo-4-oxo-pentanoic acid ethyl ester is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-bromo-4-oxo-pentanoic acid ethyl ester (CAS 54260-84-3), a certified reference material (molecular formula C7H11BrO3, MW 223.06 g/mol) for analytical method development and quality control.

3-bromo-4-oxo-pentanoic acid ethyl ester (C7H11BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
