Mea Hana Kiʻekiʻe Pyrazine CAS NO.290-37-9 Mea Hana Waena Organic Pyrazine

ʻO Pyridazine (290-37-9) me ʻelua mau ʻātoma naikokene i loko o 1,2 mau huahelu ua kapa ʻia ʻo pyridazine; ʻO nā huahelu 1,3 ua kapa ʻia ʻo pyrimidines, a he mau isomers lāua ʻelua o pyrazines. He kristal kala ʻole ʻo Pyrazine, he kiko heheʻe 54 ° C, he kiko paila 115 ~ 116 ° C (768 mm Hg), he nui ka wai pili 1.0311 (61/4 ° C). He ʻala like kona me ka pyridine. Hiki ke hoʻoheheʻe ʻia i ka wai, ethanol, ether, a pēlā aku. He kumu nāwaliwali loa ʻo Pyrazine. Ua like kona mau ʻala me ka pyridine, he mea paʻakikī loa ia e hana i nā hopena hoʻololi electrophilic, a ʻoi aku ka ikaika i nā nucleophiles. Ma hope o ka pani ʻia ʻana o ka hydrogen ma ka ʻātoma kalapona e kahi hui methyl a halogen paha, ua ikaika ka hydrogen ma ka halogen a i ʻole ka hui methyl. Hiki ke hoʻohui ʻia nā Pyrazine a me kā lākou mau derivatives e nā ʻano hana like ʻole.
