Chemical Structure
Description
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, trifluoroacetic acid ethyl 2-fluoro-2-(pyrrolidin-3-yl)acetate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 289.22 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.
