Chemical Structure
Description
The occurrence of Butyl 3-bromo-2-oxopentanoate 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.
Butyl 3-bromo-2-oxopentanoate (CAS 1171127-36-8) is a high-purity analytical reference standard with the molecular formula C9H15BrO3 and a molecular weight of 251.12 g/mol.
Based on its molecular formula C9H15BrO3, Butyl 3-bromo-2-oxopentanoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 251.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
