Hoʻolauna
ʻO ka 1-Cyclopentene-1-carboxylic acid he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

ʻAno maikaʻi:
ʻO ka 1-Cyclopenten-1-carboxylic acid he wai melemele ʻole a māmā paha me kahi ʻono ʻawaʻawa. Hiki ke hoʻoheheʻe maikaʻi ʻia a hiki ke hoʻopili ʻia me nā ʻano mea hoʻoheheʻe kūlohelohe e like me nā alcohols, ethers, ketones, etc.

E hoʻohana:
Hoʻohana nui ʻia ka 1-cyclopentene-1-carboxylic acid i ke kahua o ka synthesis organik. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomaka, catalyst, a me ka ligand no ka synthesis o nā pūhui organik.

Hanana:
Aia nā ʻano hana like ʻole no ka hoʻomākaukau ʻana i ka 1-cyclopenten-1-carboxylic acid. Loaʻa kahi ʻano hoʻomākaukau maʻamau e ka hopena o cyclopentene a me carbon dioxide. ʻO ka ʻanuʻu kikoʻī e hana i ka cyclopentene a me carbon dioxide ma lalo o ke kaomi kiʻekiʻe, ka wela kiʻekiʻe a me ka catalyst e hana i ka 1-cyclopentene-1-carboxylic acid.

ʻIke palekana:
ʻO ka 1-cyclopenten-1-carboxylic acid he wai hiki ke ahi ma ka lumi wela a pono e mālama ʻia mai ke ahi a me nā kumu wela. Pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā oxidants, nā ʻakika ikaika a me nā kumu ikaika i ka wā o ka hoʻohana ʻana a me ka mālama ʻana i mea e pale ai i nā hopena pōʻino. Inā pili me ka ʻili a i ʻole nā ​​maka, holoi koke me ka wai nui a ʻimi i ka lāʻau lapaʻau. Ke hoʻohana nei i ka 1-cyclopentene-1-carboxylic acid, pono e hahai pono i nā kaʻina hana palekana.
