Chemical Structure
Description
The molecular framework of 3-bromo-4-methoxy-4-oxobutanoic acid (C5H6BrO4) is characterized by a carbohydrate-derived structure, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
3-bromo-4-methoxy-4-oxobutanoic acid (CAS 98298-19-2) is a high-purity analytical reference standard with the molecular formula C5H6BrO4 and a molecular weight of 210.00 g/mol.
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.
