Chemical Structure
Description
The occurrence of Bromo-PEG4-CH2COOtBu 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.
Bromo-PEG4-CH2COOtBu (CAS 1807505-29-8) is a high-purity analytical reference standard with the molecular formula C14H27BrO6 and a molecular weight of 371.26 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, Bromo-PEG4-CH2COOtBu is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 371.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
