Chemical Structure
Description
The molecular framework of 2,2-Dichloro-1,1-diethoxyethane 619-33-0 D0354 Dichloroacetal Dichloroacetaldehyde Diethyl Acetal (C6H12Cl2O2) 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.
2,2-Dichloro-1,1-diethoxyethane 619-33-0 D0354 Dichloroacetal Dichloroacetaldehyde Diethyl Acetal (CAS 619-33-0) is a high-purity analytical reference standard with the molecular formula C6H12Cl2O2 and a molecular weight of 187.06 g/mol.
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.
