2-propenoic acid, 2-bromo-, methyl ester 4519-46-4 InChI=1/C4H5BrO2/c1-3(5)4(6)7-2/h1H2,2H methyl 2-bromoacrylate (CAS 4519-46-4), molecular formula C4H5BrO2 and molecular weight 164.99 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-propenoic acid, 2-bromo-, methyl ester 4519-46-4 InChI=1/C4H5BrO2/c1-3(5)4(6)7-2/h1H2,2H methyl 2-bromoacrylate (C4H5BrO2) 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.
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.
