Chemical Structure
Description
The molecular framework of Isopropyl 4-bromo-3-oxobutanoate (C7H11BrO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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.
Isopropyl 4-bromo-3-oxobutanoate (CAS 134969-44-1) is a high-purity analytical reference standard with the molecular formula C7H11BrO3 and a molecular weight of 223.06 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.
