Chemical Structure
Description
The molecular framework of trans-4,5-dichloro-4,5-dimethyl-1,3-dioxolan-2-one (C5H6Cl2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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.
trans-4,5-dichloro-4,5-dimethyl-1,3-dioxolan-2-one (CAS 116857-05-7) is a high-purity analytical reference standard with the molecular formula C5H6Cl2O3 and a molecular weight of 185.01 g/mol.
