Chemical Structure
Description
The occurrence of 2-Methoxy-2-methylpropane-1-sulfonyl chloride is closely related to a sulfone group, 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.
CATO supplies 2-Methoxy-2-methylpropane-1-sulfonyl chloride (CAS 338452-93-0), a certified reference material (molecular formula C5H11ClO3S, MW 186.66 g/mol) for analytical method development and quality control.
The molecular framework of 2-Methoxy-2-methylpropane-1-sulfonyl chloride (C5H11ClO3S) is characterized by a sulfone group, 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.
