2-Cyano-3,5-dichloropyridine wani nau'in halitta ne tare da tsarin sinadaran C6H2Cl2N2. Mai zuwa shine bayanin yanayinsa, amfaninsa, shirye-shiryensa da bayanan aminci:
Hali:
2-Cyano-3,5-dichloropyridine mai kauri ne mara launi ko kodadde rawaya. Yana da ƙananan juzu'i a zafin jiki. Yana da low solubility a cikin ruwa da kuma high solubility a Organic kaushi kamar ethanol da dimethylformamide.
Amfani:
2-Cyano-3,5-dichloropyridine yana da nau'ikan aikace-aikace masu yawa a cikin ƙwayoyin halitta. Ana iya amfani da shi azaman tsaka-tsaki don haɗa nau'ikan mahadi daban-daban (kamar kwayoyi, dyes da magungunan kashe qwari). Bugu da ƙari, ana iya amfani da shi azaman abu a cikin binciken diodes masu haske na halitta (OLEDs) da nunin crystal na ruwa.
Hanyar Shiri:
2-Cyano-3,5-dichloropyridine za a iya shirya ta amfani da hanyoyi daban-daban na roba. Hanyar roba ta gama gari ita ce amsa madaidaicin fili na pyridine tare da cyanide, sannan chlorination ya biyo baya don samun samfurin.
Bayanin Tsaro:
2-Cyano-3,5-dichloropyridine ana iya ɗaukar cutarwa a ƙarƙashin yanayin al'ada. Yana iya zama mai ban haushi ga fili na numfashi, idanu da fata. Lokacin amfani, yakamata a ɗauki matakan kariya masu dacewa, kamar sa safar hannu da tabarau. Kauce wa lamba tare da oxidizing jamiái da kuma karfi acid yayin ajiya da handling. Idan an fallasa ko an shaka, nemi kulawar likita nan da nan.
