Chemical Structure
Description
The occurrence of Bromo-PEG4-t-Butyl Ester is closely related to 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 Bromo-PEG4-t-Butyl Ester (CAS 564476-32-0), a certified reference material (molecular formula C15H29BrO6, MW 385.29 g/mol) for analytical method development and quality control.
Based on its molecular formula C15H29BrO6, Bromo-PEG4-t-Butyl Ester contains 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 385.29 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.
