Chemical Structure
Description
The occurrence of 1-Chloro-3-methoxy-3-methyl-2-butanone is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Chloro-3-methoxy-3-methyl-2-butanone (CAS 57539-98-7) is a high-purity analytical reference standard with the molecular formula C6H11ClO2 and a molecular weight of 150.60 g/mol.
The molecular framework of 1-Chloro-3-methoxy-3-methyl-2-butanone (C6H11ClO2) 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.
