ʻO kekahi mau waiwai o kēia pūhui penei:
1. Ke ʻano: ʻeleʻele melemele i ka pauka crystalline ʻalani-melemele.
2. Lae hehee: kona laula hehee o 80-86 degere Celsius.
3. Solubility: Hiki ke hoʻoheheʻe ʻia i loko o ka hapa nui o nā mea hoʻoheheʻe organik, e like me ka ethanol, methanol, a me nā mea ʻē aʻe.
Loaʻa iā ia kekahi noi i ka synthesis organik. Hiki ke hoʻohana ʻia ma ke ʻano he kumu waiwai i loko o ka synthesis organik, komo i nā hopena kemika like ʻole, a synthesize i nā pūhui organik a i ʻole nā mea waena.
Hoʻohana pinepine ʻia ke ʻano o ka hoʻomākaukau ʻana i ka calcium e ka nucleophilic substitution reaction. ʻO kahi ʻano hana maʻamau o ka hoʻomākaukau ʻana ʻo ia ka hana ʻana i ka 3-bromo-2-nitropyridine me kahi pūhui amino e hana i ka huahana i makemake ʻia.
E pili ana i ka ʻike palekana, ʻo ia ka mea hoʻohuihui kūlohelohe i loaʻa i kekahi ʻona a me ka huhū. Pono nā mālama palekana e like me nā mīkina lima kūpaʻa kemika, nā maka aniani a me ka ea i ka wā e lawelawe ai a hoʻohana. I ka manawa like, pono e mālama ʻia i loko o kahi pahu i hoʻopaʻa ʻia, ma kahi mamao o nā kumu ahi a me nā mea ʻē aʻe. Inā pili ka manaʻo a ʻai paha, e ʻimi koke i ka lāʻau lapaʻau. E hahai mau i nā hana palekana kūpono, e like me ka hoʻolei pono ʻana i ke koena a i ʻole ka ʻōpala.
