Vapors are toxic, as is skin contact. | [Description]
Ethyl 2-oxocyclopentanecarboxylate (EOCPC) is a multifunctional organic reagent that can be used as a pharmaceutical intermediate or raw material for chemical synthesis. EOCPC reacts with kaolinite to prepare intercalation compounds. It also participates in Michael reactions and diazonium transfer reactions for the preparation of other active ingredients. | [Chemical Properties]
