| | 2-Chloropyrazine Usage And Synthesis |
| Chemical Properties | clear colorless to yellowish liquid | | Uses | 2-Chloropyrazine is used in cardiotonic, in biological, drug, flavoring and perfumery industry. | | Application | 2-Chloropyrazine is used as a reagent in the synthesis of hetaryloxy benzoxaborole compounds which have antimalarial activity. 2-Chloropyrazine is also used to prepare 4,5-disubstituted 6-aryloxy-1,3-dihydrobenzo[c][1,2]oxaboroles which are broad-spectrum serine β-lactamase inhibitors. | | Definition | ChEBI: 2-chloropyrazine is a member of pyrazines. | | Purification Methods | Fractionally distil it through a short column packed with glass helices. It has apenetrating, mildly pungent odour with a high vapour pressure at room temperature.
