Chemical Structure
Description
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.
3-bromo-2-oxopropanoic acid methyl ester 7425-63-0 A838075 methyl 3-bromanyl-2-oxidanylidene-propanoate (CAS 7425-63-0) is a high-purity analytical reference standard with the molecular formula C4H5BrO3 and a molecular weight of 180.98 g/mol.
3-bromo-2-oxopropanoic acid methyl ester 7425-63-0 A838075 methyl 3-bromanyl-2-oxidanylidene-propanoate (C4H5BrO3) 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.
