CATO supplies 2,5 inverted exclamation marka-Dibromo-2 inverted exclamation marka-hydroxyacetophenone 2-Bromo-1-(5-bromo-2-hydroxyphenyl)ethanone 5-Bromo-2-hydroxyphenacyl bromide 67029-74-7 (CAS 67029-74-7), a certified reference material (molecular formula C8H12Br2O2, MW 299.99 g/mol) for analytical method development and quality control.
The molecular framework of 2,5 inverted exclamation marka-Dibromo-2 inverted exclamation marka-hydroxyacetophenone 2-Bromo-1-(5-bromo-2-hydroxyphenyl)ethanone 5-Bromo-2-hydroxyphenacyl bromide 67029-74-7 (C8H12Br2O2) 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.
