A cyclic ester containing four carbon atoms, also called a butyrolactone; used in industrial and pharmaceutical applications.
From 'butano-' (four-carbon) combined with '-lid,' a suffix for lactones (cyclic esters). Named in systematic chemical nomenclature.
Butyrolactone is so useful that it was banned in many countries as a legal high because people were drinking it; the same solvent that cleans electronic components also affects the brain.
