Chemical Structure
Description
The occurrence of (2Z,3Z)-1,4-dibromobutane-2,3-dione O,O-diacetyl dioxime is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (2Z,3Z)-1,4-dibromobutane-2,3-dione O,O-diacetyl dioxime (CAS 370071-74-2), a certified reference material (molecular formula C8H10Br2N2O4, MW 357.98 g/mol) for analytical method development and quality control.
The molecular framework of (2Z,3Z)-1,4-dibromobutane-2,3-dione O,O-diacetyl dioxime (C8H10Br2N2O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.
