Chemical Structure
Description
The occurrence of 2-Bromoethyl methanethiosulfonate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Bromoethyl methanethiosulfonate (CAS 26139-15-1), a certified reference material (molecular formula C3H7BrO2S2, MW 219.12 g/mol) for analytical method development and quality control.
Based on its molecular formula C3H7BrO2S2, 2-Bromoethyl methanethiosulfonate contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 219.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
