Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, Ethyl 5-bromo-3,3-dimethylpentanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.13 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.
