Mucobromic acid 2,3-dibromomalealdehydic acid (2z)-2,3-dibromo-4-oxobut-2-enoic acid 2,3-dibromo-4-oxo-2-butenoic acid dibromoaldehydoacrylic acid a,b-dibromo-b-formylacrylic acid 2,3-dibromomaleic aldehyde acid Bromomucic acid 488-11-9 (CAS 488-11-9) is a high-purity analytical reference standard with the molecular formula C4H2Br2O3 and a molecular weight of 257.86 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, Mucobromic acid 2,3-dibromomalealdehydic acid (2z)-2,3-dibromo-4-oxobut-2-enoic acid 2,3-dibromo-4-oxo-2-butenoic acid dibromoaldehydoacrylic acid a,b-dibromo-b-formylacrylic acid 2,3-dibromomaleic aldehyde acid Bromomucic acid 488-11-9 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.86 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
