|Section3= }} Isopropyl cyanide is a complex organic molecule that has been recently found in several meteorites arrived from space. The singularity of this chemical is due to the fact that it is the only one among the molecules arriving from the universe that has a branched, rather than straight, carbon backbone which is larger than usual, in comparison with others. == History == Both isopropyl cyanide and its straight-chain isomer, ''n''-propyl cyanide, were detected by astronomers from Cornell University, the Max Plank Institute for Radio Astronomy and the University of Cologne by means of using the Atacama Large Millimeter/submillimeter Array (ALMA) — a set of radiotelescopes in Chile —. The chemical was found within an immense gas cloud in the star-forming region called Sagittarius B2. This interestellar space is located at about 300 light years away from the galactic center Sgr A *.〔(【引用サイトリンク】 New molecule found in space connotes life origins )〕 and about 27,000 light years from Earth. About 50 individual features for Isopropyl cyanide and 120 for normal proyl cyanide (n-propyl cyanide) were identified in the ALMA spectrum of the Sagittarius B2 region. The published astrochemical model indicates that both isomers are produced within or upon dust grain ice mantles through the addition of molecular radicals, albeit via differing reaction pathways. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Isopropyl cyanide」の詳細全文を読む スポンサード リンク
